5-7/8x8-1/8" card was originally 6.25x9.5" and had white margins trimmed. Front image/design remains complete. Reverse has small bit of text off at left, but content is still legible. This March of Dimes premium was offered in Sensation Comics No. 15, March, 1943. Card features nice image of Wonder Woman with magic lasso and text "Sincerely, Diana Prince (Wonder Woman)." Back of card has postcard section with text that reads in part "This Acknowledges Receipt Of Your Contribution To This Years Presidents Birthday Celebration For The National Foundation For Infantile Paralysis." Postcard is left blank and has postage area pencil marks. This card is a larger and more impressive size than the Batman March Of Dimes card we offered in Auction 183. Light corner tip wear and aging with small spots of soiling below address lines on reverse. Still a great example and front displays Exc. Very Rare.
