I was quite surprised to see this Pola ad in the November 1982 issue of Railroad Model Craftsman.
It starts off by stating: Pola manufactures over 200 HO & N structure kits. Many of these are American designs originally published in MRR (their acronym for Model Railroader) and RMC. We are re-issuing these on a limited basis, at special prices.
Amongst the pictures it notes that the coal mine in the upper left is a Jack Work design from a 1959 issue of Model Railroader, although it doesn't say which issue. And in the lower left there is the good old Grusom Casket Co. from an E. L. Moore design in Railroad Model Craftsman. It doesn't say who designed that coaling station in the lower right, but the overall implication is that it came from somewhere in the pages of MR or RMC. I wonder if these were released in special American Designer Series boxes, or if there are any further ads with more about this series? An interesting twist. The search continues :-)
[30 October 2020 update: Vince informs me, and I confirm, that the Jack Work coal mine article was actually a 3-parter that appeared in the Oct, Nov, and Dec '59 issues of MR. And, the same ad also appeared in the Nov. '82 issue of MR.]
