This is an antique sleeve in which a 78rpm record was housed. The manufacturer was Decca, and the two-song record is unknown. I’m tired and want nothing to do with just about everything right now, so this trivial nonsense can very well go walk a yippy dog.

I have this record sleeve with a record: NICKLE POLKA (Lawrence Welk-Ben Kanter), LAWRENCE WELK And His Orchestra, #4018A and the reverse side, RAISE THE WINDOW DOWN (Ted Meyn), LAWRENCE WELK And His Orchestra, #4018B.
Nice! Such lovely, frame-worthy art!
