AI-assisted summary
Description from the seller
Greece – 20 lepta – Printing error on the back – Partially inverted impression on the gum
Greek 20 lepta stamp, depicting a winged figure, presenting a particularly interesting printing anomaly.
The front bears a normal, complete impression. By contrast, the back shows a second partial, clean, and inverted impression reproducing the Greek inscription “ΕΛΛΑΣ”, the columns, and a portion of the upper drawing.
Visual examination shows that the black ink seems to have been deposited directly onto the gum. The gum remains visible in the non-printed areas, while the black areas appear to be gum-free on the surface.
David Feldman note:
This stamp was submitted to Allan Westphall, a philatelist at David Feldman, the international philatelic auction house.
In his written response, Mr. Westphall states:
“We believe that this 20-pound Greek stamp is a true printing error.”
He nevertheless notes that it could be accepted within a larger collection.
Condition and features:
* Mint, with no visible canceller.
* Gum present on the back.
* Partially inverted back impression.
* Anomaly compatible with an accidental ink transfer.
* Professional favorable opinion from David Feldman, without a certificate of expertise.
Conclusion:
An item showing a probable printing error, documented by detailed photographs and accompanied by a favorable written opinion from David Feldman.
The exact mechanism of the anomaly and its philatelic classification remain to be confirmed by specialized expertise.
Correspondence with David Feldman can be provided to the Catawiki expert upon request.
