I didn't doubt FVM and figured there were variation, but not being the B&O-head, I needed to know which to buy for my layout. The billboard it is!
I guess, for variety's sake, I should ask - would one be able to find one of the flat door 13 great states cars in service in the late '60s? If not I suppose I should wait for a Time Saver or Sentinel billboard in a future run...
