I picked up my copy of the 1957 Lionel (Reg.U.S.Pat.Off.) catalog at the old Sanger Bros. Department Store in Dallas, Texas. It was around the time when I had just passed Birthday Milepost 11 that long ago July 4, 1957. My stepdad was out of work a lot, so all I could do was dream about that layout, as well as Super-O track too for that matter. I never really liked my O27 so sold it to a guy shortly after my stepdad moved us from Texas to his native Tampa, Florida, in January 1962, for a whopping $10 bucks! NO REGRETS!
The trains were pretty well wore out by this time. The 2-4-2 steam locomotive was missing a marker light on the front (real common) and I had brush painted the tuscan red Pennsylvania GP7 with Testor's red for "The Katy"! I cut out Deramus KATY heralds from a public timetable and glued them under the cab windows.
I recall that the guy said he was going to strip the paint off the geep and make a "GP20" out of it. Never saw the guy again (having met him one time in a North Tampa hobby shop out on Nebraska Avenue) so don't know if he ever went through with the project or not?
The father shown w/o a head walking down the stairs with his son reminds me of my stepfater. He was 6 ft. tall. If I were going to recreate the scene, I'd do it just as it's shown in the drawing including the same floor pattern, etc. I imagine most boys in 1957 who had Lionel trains dreamed about this layout when they weren't busy watching Annette Funicello (RIP) play the part of "Annette" in the Mickey Mouse Club series that aired on beautiful black and white TV in early 1958.
I'm sure this question has been asked and answered a million plus times over the years, but personally having never found it myself, I've always wondered why Lionel never reintroduced Super-O to the market?
