Ran into this vendor in the skyways of Minneapolis yesterday. He was selling really nice 11x17 ink drawings of vintage depots of towns/cities throughout Minnesota - and some ND, SD and WI. Drawings were based on historical photographs or personal visit if the structure stil existed.
I bought several representing the small towns of my grandparents that I remember from my youth and present day (Wayzata etc.) Thought would look great in my layout room.
Again, I just ran into the guy yesterday - I have no financial or personal interest - but thought I would pass it on. You can visit his website www.ArtRail.com. Just call up the town/city you are interested in and you can view drawings available for sale.
