1930s Depression Era Boy's Denim Jacket

Really wonderful pre-war denim jacket with pleat front. Donut buttons and copper domed rivets. Pleated action back. Patch pocket without flap. Inside seam reveals blue line selvedge. No makers marks apart from a stamped "U" on the button rivet. Signs of rough house play and a penchant for maybe chocolate ice cream? Missing one button and a small tear next to one button hole. Toddler size fits a chest measuring 22" comfortably. Length 12.75" Outside sleeve 10"
