You might watch eBay but you haven't seen this Route Book on there more than a time or two. This is the 1937 Cole Bros. Circus. It includes the 1935 and 1936 routes along with all the expected information in this 112 page book. I'm selling this for a friend. $85.00 firm. You can buy it on my website at www.thecircusworld.com
I also have a very rare 1892 Adam Forepaugh Route Book for sale on my website.
