I found the Traction Fan's Directory 1965. I was 13 when I got this. There was a June 1964 Traction & Models brochure with FREE as a price. It's pictured in an ad and has a photo of the Traction Terminal at Indianapolis on the cover. The text says "Traction & Models will begin as soon after the first of 1965 as possible."
The March 1968 issue had a Third Anniversary Issue banner across the top of the front cover.
Later Traction & Models added an O Gauge Railroading supplement in the center of the magazine prior to be published as a separate magazine by Casey Jones, Vane's son.
