How interesting!The Imperial Hotel has been owned by the Mackin family (phone no. in earlier message) since 1946 and they apparently have a collection of photos and such.If you were interested, you might want to contact them.
Also, the Union Printers Home is still active.Their no. is 719-634-3711.Don't know what records they have.
Additionally, the Union Printers headstones in Evergreen include the local no.Whether the Typographers Union still exists I don't know, but I'd be glad to get that info for you --I only live 5 minutes away from Evergreen.
