Ran across this today on Abe Books. Out of my league (and I'm trying to avoid ephemera anyway), but the photos of the typewriter shop are interesting to see what's on display and how they display it.https://www.abebooks.com/signed/Collection-typewriter-ephemera-including-Constitution-By-Laws/13324665910/bd
That's pretty cool! I had the fortune to speak to a descendent of the owners of a very large typewriter distributor, there is rich history there.
