Stanley in Africa pinbacks

Two 1 1/4 pinbacks c.1900, promoting the the Universal Chapter play, Stanley in Africa. The 2 examples I have in my collection are part of an 8 pin promo set. 7 of the pins had a different African animal portrayed on each pin, with an 8th pin advertising the serial.
These are in great shape and were purchased from a collector in St.Paul Minnesota. Difficult finding these in Canada. Saw a set of 4 on Hakes Auctions but no where else recently.
Enjoy
