I believe this drawing likely dates to the 1940s, and that our bugler wears a U.S. Navy uniform--the hat at least sure looks Navy to me, and U.S. is written on the pocket of his rucksack. I just love the manner of the drawing, and especially the rendering of his face in profile, with outlined hat on top and ear framed by the line of his black hair, and then this big hand holding his trumpet to his mouth with tassels like teardrops painted in this perfect blue hanging from it, all counterpointing the gun strapped to his back. So handsome!
10 1/8: x 4 5/8" and in very good condition, with a couple of tiny folds to the bottom corners and a bit of scattered staining/toning, very minor. On the reverse is a partial sketch that looks like a first stab at this drawing.
