This album was first released in 1957, see f.i. this review in “De Tijd”, August 3, 1957.
Shown is a (mono) reissue from the early 1960’s. It still has the Minigroove logo on the cover, but it’s missing from the labels.
The front cover illustration was made by Herschel Levit, an American painter, printmaker, photographer and influential design teacher at the Pratt Institute.
