Getting your submission ready

1. Fill in all the details and write a clear description

When you submit an object, you’ll see fields to guide you in providing the right information, such as: title, issue number and original title, binding type (hardcover, softcover, stapled, loose), year of publication, publisher and author name, language, etc. These fields ensure your listing is clear, searchable, and easy for bidders to understand.

Note: To determine condition, we use the following grading system:

• Mint – In perfect condition. Unread and untouched, with no visible flaws or wear. Suitable for top-tier collectors.
• Near mint – Almost perfect. May show minimal handling or printing imperfections. Clean, sharp corners and intact spine.
• Very fine – Excellent condition with slight wear such as minor corner rubs or subtle spine creases. Bright, glossy cover.
• Very good – Light wear including small edge tears, mild creasing, or slight fading. Structurally intact and complete.
• Good – Moderate wear. May include visible creases, surface soiling, or small cover defects. No missing pages or content.
• Fair – Heavy wear. Significant creasing, tearing, or discoloration. Still readable but clearly aged and fragile.
• Poor – Severely worn or damaged. May have missing or detached covers, water damage, or major tears. Must be clearly described.

Please also use the object description field to share:

• Unique features or notable history of the object
• What is included/not included (e.g. packaging). For objects like sets or albums clearly state if they are partial or complete.
• Where the object came from/how it was obtained
• If the object has any flaws

Tip: The more detail you provide, the easier it is for bidders to understand the value of your object – and the more likely it is to sell. Find here more tips on how to write a clear, accurate description. 

📌 Examples of well-written descriptions:

• Example of a comic book description:

Editoriale Corno, Alan Ford No. 1, May 1969, first edition. Paperback, 17x12 cm. Newsstand or warehouse copy, front cover smooth and flawless. Spine in perfect condition. The back cover shows marks from a binding strap on the right margin and light pressure marks. No reading crease on the cover; interior pages are bright white. No restorations.

• Example of an original comic page description:

Pratt, Hugo - original page n. 108 published in Argentina in 'Misterix' n. 443, Editorial Abril, 1957.

Pencil and ink on cardboard, 48x32.5 cm. 

Excellent condition.

Books & (Dutch) published page shown for reference only; books not included.

2. Great photos matter

Photos are the first thing bidders see – so make them count! We recommend including at least 3 high-quality images that clearly show the condition and details of your object. This helps bidders make informed decisions and increases your chances of a successful sale.

Your photos should include:

For all submissions:

• Front and back covers and the spine (with visible edges)
• Any flaws (creases, tears, repairs)
• Signatures, COAs, and publisher/print information

For grouped submissions:

• Photo of all objects together as well as individual shots

Tip: Avoid photos with people, selfies, or screenshots. Use a neutral background (white or black), avoid low-quality or stock images, and aim for natural lighting. Find here more tips on how to take professional photos.

📌 Examples of good vs. bad photos:

• This image is effective because it’s clear, well-lit, and professionally framed. A straight-on angle, sharp focus, and clean background allow buyers to assess the object confidently reinforcing trust and quality.

• This photo is ineffective due to poor lighting, distracting background, unclear framing, and lack of detail. These issues can make the listing feel unprofessional or misleading, which may reduce bidder trust and lower the final sale price. 

• This image is ineffective due to poor lighting, low clarity, and an off-angle shot. The screenshot format and incorrect aspect ratio also make it unsuitable for Catawiki’s layout, preventing accurate assessment of the object’s condition.

3. Additional proof of authenticity

We pay extra attention to ensure authenticity of high-value and autographed objects to protect bidders and ensure a trustworthy marketplace.

For high-value or signed submissions, additional documentation may be required:

✔ Certificates of Authenticity (COAs) for signatures over €500 in value
✔ Provenance documents such as auction receipts or notarial deeds
✔ Comparison with known examples (our experts will assist)

✔ Photo of the publisher limited /signed certificate or number engraved (if figure) or page (if book) 

📌 Examples of proof of authenticity:

• This image shows a Dynamic Forces Certificate of Authenticity (COA) and its corresponding holographic sticker. 

• In this case, the sticker was used to seal a Signed US Comics protective sleeve, while in other cases it may be applied directly onto the certificate itself.
