AMERICAN classics I AMVETS? I Lot of 5 Assorted Greeting Cards I Litho in USA

Here is a set of 5 American Classics greeting cards, vintage 1993, which I *believe* were issued by AMVETS (American Veterans) National Service Foundation. They are soft paper, versus cardboard/sturdy paper, and are stamped Litho in U.S.A. with a copyright date of 1993. They are in excellent/new condition, HOWEVER, there are only 3 envelopes, and not 5. Photo 1, main image Photo 2, front of cards (shown with envelopes) Photo 3, back of cards Photos 4-5, close-ups of brand/copyright info on rear of cards Photo 6, fronts of 3 envelopes (backs are perfect as well) Photo 7, interior of all cards Photo 8, construction of cards, they fold out like a piece a paper Photos 9-12, interior messages on each card - the "Just a note" card in photo 8 is blank inside, as shown Photos 13-16, trademark info for "American Classics" in the greeting card category, owned by AMVETS. They owned two trademarks in this category, "American Classics, " and "American Apple Pie Classics." In the U.S. Patent & Trademark Office's electronic database, in the "TSDR" or "Trademark Status & Document Retrieval" section, you can often see specimens. Unfortunately for this one, the specimen is simply a postage card with AMVETS logo, and not a specimen of the greeting card itself. But if you look at the "Apple Pie" trademark specimen, it is very similar to these cards, and in fact does not have the AMVETS logo on it either. So I can't be 100% sure, but I believe these were AMVETS, from 1988-2010.
