This ad ran in FM forever and is my favorite records ad. I loved that Wally Wood cover art (top six LPs) and imagined the records had great audio adaptions of those Verne and Wells tales! I never did get them (and don't know what I'd do with them now), but I have some color photos of the covers.
This notice is from the April 16, 1966 issue of Billboard. The LPs were rereleased on Wonderland Records in 1974.
