I own one record, a used Chuck Mangioni record I bought as ironic art from a goodwill that sits in a frame on my wall. So I'm afraid I'm adding to this statistic somewhat inadvertently.
I have Judas Priest's "Sad Wings Of Destiny" and Dead Kennedy's "In God We Trust, Inc". I bought them back before vinyl died and have held on to them as keepsakes of years gone by. I haven't had a record player since the 90's so I guess I'm part of the 50% as well!
I bought as a record to play Small Faces Ogden's Nut Gone Flake back in 1978 (released in 1968) .. the cover is a gem, round carboard layers with a common one inch spine all modelled on an old school tobacco tin.
As one of the few not square record covers released I have it out in a double perspex holder and rarely handle it as it wouldn't take much to tear the hinging 50 years on after its creation.
