I am looking for Tom Fawell EMD ad artwork. If you ever run across some let me know. I have looked everywhere and cannot find them besides some ads once in awhile. I actually found one of the top two that I wanted at a local train show.

Not sure if this helps, but old issues of Trains had some, always more interesting than the usual ads. I always liked the ads myself.
