AI-assisted summary
Description from the seller
1. The centerpiece: Block of 4 with "Abklatsch" (Mirror-image printing)
Description: A unique block of four stamps (Territorios Españoles del Golfo de Guinea) with a spectacular printing error on the back. The red overprint ended up mirrored on the gum side.
Expertise: This is known in philately as an 'Abklatsch' or 'Offset' error. This occurs when the press keeps running without paper being fed, causing the ink to transfer onto the counter-plate and then onto the back of the next sheet of paper.
Rarity: The fact that this is a complete block of four makes it extremely rare. Most of these kinds of errors are destroyed by the printer's quality control. For a specialized collector this is a museum piece.
2. La Marche Verte - Jubilee issues
Theme: Stamps commemorating the 2nd anniversary of the Green March (1977).
Notable: One specimen bears the black overprint "2ème TRANSAT DES ALIZES".
Condition: The stamps are in MNH condition (Mint Never Hinged), with full original gum and the original paper margins. The handwritten date "Octobre 1977" on the margin adds extra historical context.
3. Protectorado Español (Spanish Protectorate)
Content: Various series of the "Correos Marruecos" under Spanish administration.
Details: Includes among others the "Sobretasa Obligatoria" stamps (mandatory tax for war-wounded in Africa) and stamps with the overprint "TANGER".
Historical value: These blocks are essential for the study of the administrative and postal distribution of Morocco at the beginning of the 20th century.
Conclusion for the collector:
