Ran across two Columbia " Regent" ads today and I leapt to the scanner before I misplaced them. The Regent didn't figure in the Columbia ads for very long, but in 1910-11 they pushed it for all it was worth. Here's the glamourous Lina Cavalieri who was the height of chic in 1911. And height would be the operative word:if we believe the scale of this ad she was about eight feet tall.
This magazine was badly faded so I could either bring up the text or make Lina and the Regent look good so I chose the latter.
The second ad has clearer text, but lacks the glam quotient. I'll post it soon.
