Nice original vintage Chippewa boots sign. It is reverse painted on the glass and backed with to give it a mirror look. There are a few imperfections, see the up close photos. It looks to have some real age to it.
I would guess 75+ years based on the frame. The sign does have the registered logo in the design so that puts it after 1946. So I would estimate this right around the 1950s. I put new pins and sealing tape on it so it is solid and ready to display.
