Vintage 1950’s Pendleton Red Knit discount Zip Front Vest

Vintage 1950's Pendleton red zip front sweater vest. This tag is certified from the 50's by Vintage Fashion Guild. Probably hand knit. Round front pockets. Cozy mid-gauge pure virgin wool. Some stretch. The tag has a cut but otherwise in good vintage condition, no snags, pilling, stains, rips or smells. A very choice piece; the only one like this I have seen.
Measured flat: 18” pit to pit, 26” discount overall length
