Nirvana for sign collectors - a large stack of obsolete wooden interstate signs with the state names. I-80N became I-84 in 1978. This photo was taken in 1983, so these signs sat undisturbed for five years! (Photo by Michael Summa). |

An older style black on white state route marker. This style sign was used from the late 1940's into the 1960's. It is still used on big green sign assemblies, but not as freestanding reassurance signs. This particular sign is probably from the 1960's given the fact that it has a Scotchlite reflective background (Photo by Joe Koehler) |
