Although the postcard states this was on US-41, I don't think it is what we know US-41 to be today. An old topographical map puts the location of the Isle Royale Copper Company mine near Dodgeville, which would fit the general description of the location described on the postcard. You will note Copper County Mall is nearby and I have a page on that also if you follow the link on this page. At any rate, this attraction is long gone. The last artifact I could find on this place is a menu from 1968. I think it may have lasted into the 1970's but I am not sure.
