I have a copy of this which might match your description. It is in a heavy vinyl mono with '47W63rd' but no deep groove, RVG but no ear on the vinyl and with 'High Fidelity' on the back cover on the top left, no address on the bottom, laminated front. I think it's a very early Liberty from 1966. Sound quality is absolutely superb by the way - better than one would ever expect from the Liberty era (but some of these reissues can be very good indeed). I believe the story was that after the sale to Liberty, there was a big stock of old labels and they used them up with the 'new' non-Plastylite vinyl.
Somewhere in the rack I have a (presumably original) 47W63rd deep groove mono with ear but it's currently elusive. Sorry !
