ACLs already existed in the late 30's. Like early swimsuit lady 7-ups with a u7p embossed in the neck. I got similar looking bottles dating back in the 20s or 30s.

Just want to share my earliest 8 bubble swimsuit lady with a u7p emblem in the neck. The back label says " A cooler off, a fresher up." The earliest back label. This was released in 1937.
