There is a collection of Brownies, and all of the turn of last century photo advertising ephemera and even small doll figurines, that goes on display intermittently at different Toronto area spring camera shows from year to year.

The shows in question are run by the Photographical Historical Society of Canada.
They have a web site,
On there is a reasonable back archive of their old newsletters.
I know they ran an article on the collector sometime in the last few years. He has quite a ton of stuff Brownie related.
