Old sign

This has been with my family for as long as I can remember....I seem to remember being told it came from Cripple Creek, Colorado but not sure. just want to find out anything about it. heavy metal frame,glass face and was obviously a business sign, on the reverse appears what would have been a matching face now gone but two spots for light bulbs are present and would be no problem to rewire and light back back up.
any info would be great.

Thanks for looking.
