Lot 20326 – 1934 10p Brown/Violet Pro-University UNWATERMARKED Block of Four Mint

THE PRO-UNIVERSITY UNWATERMARKED 10 PESOS IN BLOCK OF FOUR

1934 10p brown and violet, without watermark, a magnificent block of four, lightly hinged at top, outstandingly well centered and remarkably fresh. A very rare and desirable multiple of this rarity. A great rarity of Mexican modern philately (no multiples of this stamp were gathered in the Eric Koenig collection). As this is the first time that we see a block of four of this stamp, we have checked with an expert of Mepsi about the rarity of this item, and we have been informed that this is the first example of this multiple seen by him. Scott $13,000 as singles hinged (two stamps are n.h. in this example). Sold for $27,000 hammer price in December 2003 (Cherrystone, New York, lot #2380). Cert. Mepsi (2023).
