c.1970s note card opens to 6.75x8.75". Interior has wonderful pencil and fiber tip pen drawing on top half of Uncle Scrooge waving from coin-filled wheelbarrow which is being pushed by Donald and his nephews Huey, Dewey and Louie. "Hi, Mr. Matetsky - We Deeply Appreciate Your Interest In Us Ducks!" handwritten text above w/additional text below scene reading "- 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 is easily removable. A few barely noticeable lt. tan dots at lower right side margin edge, but would mat and frame for a VF display. 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.
