I was doing some research on the name and era that Uncle Frank's was built in... Why? Ummm, just cause... (the librarian in me coming out i guess ;-)
Anyways, I found one of those goldmine links with amazing historical pictures, all of Thunder Bay and the Northwestern Ontario area. I did a few searches and quickly found a few good ones...
CNR Ticket 1938
Gold Rock Mine, (~1938)
Port Arthur's Docks and C.N.R. Station 1945
