Rick, welcome aboard... I hope to see A1G increasing in popularity as well.
It's certainly easier to assemble an accumulation of these cars than
Micro-Trains cars!
I'm not an expert but I believe that all A1G cars were pad or screen
printed and there was no decaling or hand decoration involved. There was
just too high of a production run for that to be practical.
There will be a page or two devoted to the A1G (more like the "one and a
halfth generation") kits on the A1G site, eventually. My extensive travel
schedule has yet to slow down, but it's just a matter of time before I get
back to the webmaster gig.
