Order Painted Western Shirt

Wonderful 1930-1940 gaberdine western shirt with painted scenes of bucking bronc, person riding a horse, and a horse looking at a skull. Does have all it's buttons, but was too small for my 7/8 dress form so only button a few. I am thinking it is size 4 or 5. Shoulder pads have seen order better days, but you can replace those. From shoulder to shoulder it is 15". In excellent condition.
