This advertisement from Intermountain's Trainfest flyer got me to thinking just how far freight car modeling has come in the 30 or so (plus or minus) years since the "resin revolution" ran headfirst into the "prototype modeling" revolution. Can you even imagine a flyer like this even from a brass importer or craftsman kit maker back in the dark ages before the 1980's, much less from a mass production plastic freight car vendor?
