I acquired these decals ages ago from one of the most reputable rail memorabilia dealers in the country, so I know they are authentic. But what were they used for? At three inches in diameter each, they are about the right size for luggage stickers, but most luggage stickers have a little more than just the railroad logo.
To add to the mystery, I also have this twelve-and-a-half inch decal that, except for size, is identical to the three inch ones. Was this put on office doors? Automobile doors?
This style of goat was used between 1936 and 1967, but not always in these colors. Before 1957, the letters and outside stripe of the logo used on most advertising were either black or green. From 1957 to about 1965, GN issued timetables with deep blue covers and logos that match the blue on these decals. That’s not much to go on, but it leads me to suspect the decals are from the late 1950s or early 1960s.
