It's just weird that RCA Victor, releasing a 1955 narrative kiddie record of The 500 Hats of Bartholomew Cubbins by Dr. Seuss, would assign cover art to Flora instead of using Ted Geisel's original figures. Probably a copyright permissions—or lack of them—issue. Still, it's weird. You'd think the Seuss rights owners who gave RCA permission to use the literary work would object to another artist's commercial portrayal of the classic illustrations. Flora's great, but Seuss is—Seuss!

Above is a rare Flora mid-1950s cover. (Granted, not one of his more spectacular illustrations.) We don't recall where we obtained this lo-res gif, but it's the only proof we've ever seen of this 7" EP's existence. We've been trawling for it on eBay and thru online rare vinyl dealers for years, with no success.
