c.1970s greeting card with printed front cover art of moonlit swamp opens to 6.75x8.75" blank inside which has wonderful pencil and fiber tip pen drawing on top half and handwritten note on bottom half. Top half has image of Uncle Scrooge waving from inside of coin-filled wheelbarrow which is being pushed by Donald with Donald’s three nephews at right side. Handwritten text at top “Hi, Mr. Matetsky-We Deeply Appreciate Your Interest In Us Ducks!” with additional text just below scene “-And So Does Carl Barks”. Handwritten text on bottom half reads “Dear Mr. Matetsky-I Wish To Thank You For Your Generous Valuation Of My Duck Paintings. I Try To Make Each One As Good As My Skills Will Permit. You Certainly Make Such Hard Work Worthwhile. Gratefully Yours, Carl Barks”. Card has been glued to mat board but easily removable. A few barely noticeable lt. tan dots at lower right side margin edge, but image and text area will mat and frame to VF+ appearance. Wonderful specialty art by the creator of Uncle Scrooge and long time Donald Duck comic book artist done for a renowned collectibles expert, historian and author Harry Matetsky.
