Vintage Hallmark Christmas mouse brooch. 2" x 1.5" Super cute vintage Hallmark Christmas mouse brooch. It's made from a grey plastic, with painted accents. The mouse has a happy little smile, and he's wearing a red and white Santa hat, and a red and green striped sweater. This hat has a gold tone jingling bell attached, that really jingles! Great piece of vintage nostalgia, just in time for the holidays!
