Wow, great photos of the early Acmes, never seen them before. I prefer the late 20s style. Very interesting!
I too really enjoy Acme and Wiley signals. I have a restored Wiley in my sign room that brings much enjoyment and comment. I also have a few photos of vintage and restored Acmes and Wileys on my site on the Misc Highway Stuff page:
