VTG HANDMADE THICK WOOL HANDKNIT SWEATER GREEN & WHITE BUTTON CARDIGAN IRISH ? S.

This is pre-owned and in great condition for it's age. If I had to guess, this was knitted between 1960-1980. It has an Irish feel to it with the pattern. It looks to have a shamrock design in it along with another type symbol but not sure what it is. There are some very tiny light stains in some of the cable knitting (see all photos). The measurements are:

Armpit to armpit 17.5"

Shoulder to shoulder 15"

Shoulder to end of sleeve 22.5"

Top of back collar to bottom back  25"

I would size this as a small. And, I'm pretty sure this is one-of-a-kind.

Thanks for looking and let me know if you have any questions.
