American Red Cross - Soliciting Funds - Miscellaneous - This vacuum cleaner, operated in front of the New York Public Library reaped in Red Cross contributions May 25, 1917. So great was the eagerness of the people to have their coins taken in by the cleaner that the bag inside the vacuum cleaner had to be emptied several times. The workers from left to right are: Miss Edith Van Tine and Mignon McGibney holding the tube. The soldier and sailor with the aid of their megaphones are urging the people to hand in their contributions fast besides explaining to them this novel idea
