I searched for uncut Topps sheets from 1964 and I found this image and analyzed it.
Since I don't know the provenance of said sheets, we'll just have to accept that these are real and weren't changed at some point during printing. With that said, the blocks of cards outlined in red appear on the sheets 3 times. The cards outlined in blue appear only twice (I realize it's tough to make heads or tails out of the red and blue, so simply look to the far left and right edges to quickly make it easier on your eyes).
The Curt Flood card is highlighted in the yellow circles, and he appears in the blue sections. What's funny is, if he's a short print, then so are HOF'ers Yogi Berra, Ernie Banks, Lou Brock, Eddie Mathews, Walt Alston, Joe Torre, 'All Star Vets' (with Killer and Nellie Fox) and Hoyt Wilhelm, plus 2 separate leaders cards featuring Sandy Koufax and a couple of others with Hank Aaron, Willie Mays, Yaz, etc., on them.
Since all anybody ever wants to talk about is Mickey Mantle, I'll note that he appears 3 times.
