MAD Magazine Sid Grid Parody and Creation of First Crossword Puzzle Stamps MINT!

This listing is for a genuine United States postage stamp and a rarely seen parody stamp issued by MAD magazine commemorating the development of the crossword puzzle. The MAD magazine stamp is a cinderella stamp printed over 55 years ago. It was not issued by the USPS and is not valid for postage. Both stamps are in mint, never hinged condition. (They are not crossword puzzle books!) FREE clear plastic protective display holders included! Shipping discount offered on multiple lots paid for at the same time on a single invoice, so please view my other listings. Thanks for looking! 
ATTENTION BUYERS: ALTHOUGH MOST ITEMS ARE SHIPPED THE SAME DAY OR THE NEXT DAY, DUE TO THE PANDEMIC, THE DELIVERY AND ARRIVAL TIMES MAY BE PROLONGED. THE USPS HAS OFFICIALLY ANNOUNCED DELAYED DELIVERY TIMES DUE TO DECREASED TRANSPORTATION, SO EBAY’S ESTIMATED DATES FOR ARRIVAL TIMES MAY BE SOONER THAN WHAT SHOULD BE EXPECTED. PLEASE MESSAGE ME DIRECTLY WITH ANY QUESTIONS BEFORE OPENING A CASE. THANK YOU FOR YOUR PATIENCE AND UNDERSTANDING AND BE WELL!
