i've never seen the first edition - belmont - mmpb, which has vastly better cover art, but this belmont tower printing was pretty common in the yuk-of-gb-&-ni (? or just in england??) for a while, and *may* have been re-covered as a thorpe & porter-connected flamingo imprint uk p/b - or perhaps bearing a flamingo logo + 30p(?) price label.
(keying in the contents, authors, & first publications is boring, but it makes all of these pieces of information searchable here on bookcat, which a picture image doesn't.) (this comment is from another edition of this book)
