Vintage Long Sleeve Button Down Sweater by Grant Crest

Here is a super cool vintage sweater from the 60s/70s by Grant Crest. 65% wool, 35% polyester. Off white, oatmeal color with handsome knit pattern. Five button front. This one is fairly heavy weight, warm and comfy. There were a few areas of light staining. The worst of which is shown in pic 4. I treated them once and they got lighter, so I'm hoping with a little effort on your part, they will be gone completely. It's in otherwise excellent condition with tons of life left! The tag says Large, but here are the measurements taken laying flat. (refer to the last pic above to see how I measure shirts)

Chest (armpit to armpit) 22"

Sleeve 24"

Length 28"
