United States, Scott #1435b, used(o), 1971, Celebrating a Decade of Space Achievements, left stamp shows the earth and sun from a moon landscape, and the right stamp shows a lunar rover, contiguous pair, value: 8 cents, lithography and engraved, Giori Press printed, perforated: 11, no phosphorus, black, blue, yellow and red, Scott 2019 Catalog Value: 50 cents, very slightly off-centered, double strike cancels, both very faint, red-inked, double-rimmed, circular, socked-on-the-nose cancels, one a half circle cancel on the lower right of the left stamp and shared by the right stamp on its lower left corner, the second a quarter circular corner cancel on the lower right of the right stamp, with both cancels, the lightness of the cancels leave the main images on on both stamps remarkably clear, sound back, one major pulled perforation on the lower right of the left stamp, with ragged perforations along the top of both stamps, and on the lower left of the left stamp, centering and image clear cancels warrant a selling price premium, but damaged perforations call for an adjustment, so a wash. This is not a 'bait-and-switch;' the stamp you see will be the one you receive.
Please review my terms of sale. If you are not ordering from the United States, there is a $US1.50 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 $US0.66 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.
