This sleeve is a cover for a 45 RPM record. Formally, it is a light blue sleeve with white, blocky text. The text is the logo for Arista and has bottom text with copyright information. This piece is a landmark in graphic design history because it marks a point where experimental type and constructivist styles become an identity for brands, past just album covers.
Found a nearly destructed record sleeve nearly identical to this in old record collection. This image specifically is from eBay and is the closest thing I could find.
