Bill,
The "artwork" is just those Instant Buildings from Walthers, that I had reduced 50% for N scale, cut them out with an x-acto knife, & glued them directly on the backdrop. I would love to try what you're talking about, but my printer is...well...I don't think I can use words like that on this forum...
Tyson,
Don't feel bad...I've been working on this microscopic layout for a year now!
(the whole thing would probably be a leisurely evening's work for Shamus!)
