Spain, Scott #C75 (EDIFIL #713), used (o), 1936 air mail, 40th Anniversary of the Association of La Prensa (Press Association of Madrid), stamps shows the Allegory of the Association , an Eagle and a Newspaper, 5 centimos, photogravure, perforated: 13½, black brown, Scott 2019 catalog value: 25¢, nicely centered, triple strike cancels, all, quarter hexogonal corner cancels, the main on the bottom right corner with some mailing details, the second on the top right corner, and the third on the lower left corner, all cancels are well away from the main image; centering and offset cancels warrants a selling price premium. This is not a 'bait-and-switch' offer. The stamp you see is the stamp you will get.
Please review my terms of sale. If you are not ordering from the United States, there is a $US1.45 additional postage expense that needs to be added to the price of the stamp. If you are ordering from the United States, there is only a $US0.63 added postage expense. Also, if you make additional purchases from my offerings, they can all go in one mailing at no extra shipping expense for the added purchases. I will send the purchase by US first class mail, since the relatively low value of the stamp does not warrant signature or tracking mail. Hence the buyer assumes risk of loss or non-delivery. I will keep a scan of my mailing to verify that the correct mailing address was used. If not satisfied, return the stamp to me at your own expense, and I will refund the cost, but not my postage to you. If the stamp is not as described, I will refund the cost and reimburse you for postage both ways.
By way of reference, I am an American Philatelic Society member (195176) and an American Stamp Dealers Association (ASDA) member. Thank you for looking, and I hope this is the perfect stamp to fill that gap in your collection.
