Jane, the woman in the middle with the young lad in front of her, was married to Arthur McKinney. Arthur was a route salesman for a candy distributor in Waukesha county, Wisconsin. At the Ladies of Waukesha annual picnic, Arthur arrived with cartons of Fleer's Double Bubble, and before you knew it, the bubble blowing contest began. Jane of course had the advantage because there was always Double Bubble around the house, and she liked the comic wrapper. But though it looks from this photo that she will be the winner, the prize actually went to Sandy Harper, front left. Sandy took home the cartons of Double Bubble and O'Henry bars. Her dentist was probably very happy.
