This is a vintage 1964 sewing pattern from 1964 McCall's 7223 for girl's and boy's Raggedy Ann and Ragedy Andy costumes including some absolutely terrifying wig masks.
These are a bit before the early 70's raggedy ann costume of my very first Halloween, but I think they'd be outrageously cute vintag-y style costumes.
This plan is for kid's size 10-12, 28-30" around the chest, 24-25" around the waist. These patern pieces are roughly cut out about an inch around each piece, it doesn't look like they've been used. The envelope is in two pieces, no longer useable as an envelope.
