(July 2000) York, PA. Pennsylvania appears to be putting the state name back on its interstate signs. Now all we need to see is an I-99 sign with Pennsylvania on it (Photo by Alex Nitzman).

Embosssed US highway sign from the 20's or 30's. This sign is not reflective and does not appear to have ever been used. (Collection of Robert Edgar).

Very old state route marker. Pennsylvania used the "ROUTE" logo from the mid 1920's through 1937 or 1938 according to official highway maps. The 1939 official highway map shows a cutout keystone sign with a "PENNA" logo. The PENNA signs were used into the 1950's. (My collection)
