Here is an 1849 broadside poster advertising auction books for A.P. Burt at the Cheap Bookstore located at "No 7 Baltimore Street between the Bridge and Center Market". The broadside is framed in an old lemon gold frame with wood backer boards. I have not examined the poster / broardside out of the frame. The margin around the print is not even. The broadside in the frame is 13.5" high x 7.5" across. I have not seen many broadsides advertising books. This one is amusing and charming. It would be a nice addition to an advertising collection or a wall hanger for a book collector.
