booster bag
 n.— «Friday, the 13th inst., was unlucky for the mother-and-daughter team, according to arresting officers, who said they followed the two on that day in a downtown department store and watched them take…goods. All was stuck in a booster-bag, the officers said, and later wrapped into parcels in the ladie’s rest room and placed in a shopping bag.» —“Mother Faces Burglary Trial With Daughter” Los Angeles Times May 21, 1927.
