Here is a pin back button that is 1" in diameter. There are 3 available, being sold separately. Third one has a little more wear and will be sold last. All are in excellent vintage condition.
The pins are from the early 1960s and about saving the St. Louis streetcars, which were systematically being phased out.
Please magnify photos and ask me nay questions you may have. Sold as found.
Thanks!
