Calling all vinyl lovers!  The Dewey Decimal System geek in me loves these little cards which inventory a (now) vintage album collection.  There are hundreds of extra and blank cards for your own catalogueing, or just spend hours perusing and appreciating someone else's significant collection. 

• Black vinyl case from The Recordplate Co in Pasadena, California

• 1950s?

• Cover is 14.5" x 6.5" x 1.25"w

• Cards are 2.5" x 5"

• Some wear and tear at the edge, consistent with use and age
