Campus Virgin Wool vintage varsity Letterman Cardigan Sweater with Patches & Metal Pins

Off-white/ivory color sweater with chenille big M letter, sleeve stripes, & numbers 52 in dark navy blue & red

No size label, but appears rather small

Approx. measurements laying flat:
Buttons are all intact. It doesn't appear to have been worn much, in my opinion, even the ribbed cuffs look good.

 I found some minor age/storage discoloration on the back (please see close-up).  The metal pins also have some discoloration.
