California CSAA US route 101 autostrada cartello stradale auto club AAA San Francisco

I've seen only one CSAA yellow-logo US-101 shield, and it isn't nearly as nice as this one! Made to the exact standards as used between 1928 and 1934 along this historic highway. US-101 still exists in California, though it has been truncated between San Diego and Los Angeles, being wholly replaced by interstate 5.
