Butterick 3372 is a girl's pattern for Halloween costumes. The envelope marked "Size B" which I believe means that it includes all sizes. The instruction sheet clearly states that this pattern contains the girls sizes. The pattern is probably very versatile, it contains versions of a bunny or rabbit, an animal (perhaps a leopard or bear), princess, witch and clown. The patterns also contain hats for most of the costumes. It could probably be used to make many different variations.
Pattern is uncut and complete. Envelope has a large tear on the front and wear on the corners, as well as a few stains. Instructions are also complete. No copyright date.
