From a customer's Vinyl to CD, these are the paper sleeves from a set of 10" 78rpm Vinyl Record-at-Home Vinyl Records (which are actually acetate dubplates with a metal core). I've scanned the front and back of the slipcovers with dated advertising from the year of release, which I'm guessing is the late 1940's early 1950's.
Do You Have Some Record-at-Home 78's in your closet?
