1.25” with narrow brass rim surrounding color image of full figure kewpie standing on a design of bricks and with slogan “Good Luck To Our Soldiers’ Home.” Cello has small 1/8” spot on left side of kewpie’s head and another faint 1/16” dot at far right plus a pair of vertical scratch lines at far right. Reverse of the piece is entirely covered in brass and there is a horizontal bar pin. The only vintage button we recall seeing to picture a kewpie. Fine and Rare.
