I found these photos in the blog - "History by Zim". The first is 1922 near Chicago - Two bathers are escorted off the beach by a police woman for breaking a law banning "abbreviated bathing suits." If you look in the background there are others being rounded up - it must have been some kind of daring "sit in." The original caption on the second photo reads: "Bathing beauties being arrested for defying a Chicago edict banning abbreviated bathing suits on beaches." The shame!
