It's a 1955 Greyhound Scenicrusier Bus, produced from 1955-1969. From the days when Buses were the way to see the USA!. I also have another toy today, in the second picture, do you remember Wiz-z-zers? This one has seen better days (had to tape it together). Found it the other day cleaning out yet another box or old toys. I remember playing with these for many hours.
