This original fold-out advertisement card depicts Singer’s treadle sewing machines framing in a view of the Pan-American Exposition of 1901. The card stands up and opens to form a window looking down on the exposition. The back of the card features an advertisement from Singer. It is 6.5″x4″ when closed and 15″x4″ when opened up. The card is in great condition – especially for being over 120 years old!
