Copyright details

• This promotional combination bookmark/calendar was a promotion for Chesterfield Supper Club and Chesterfield cigarettes in 1947 and can be dated by the calendar on both sides. The die-cut piece has Perry Como on one side and Jo Stafford on the other. There are no copyright marks on either side, as can be seen in the photo links. It is well within the free license timeframe.
• It was created for distribution to the radio show's listeners to induce regular listening and also to promote the Chesterfield brand of cigarettes.
• Using a timeframe for the show, it was produced after 1946 but before 1948: Co-hosting of the program by Jo Stafford did not begin until 1946 and Peggy Lee did not begin until 1948.

There is no evidence of any copyright claims for the item.
