The United States Postal Service (PSP) has honored iconic Bay Area lowriders with a new stamp named "a rolling canvas of art" in partnership with the San Francisco Lowrider Council, an advocacy group founded by Roberto Hernández that promotes and preserves lowrider culture. The stamps, which feature iconic vehicles such as the 1958 Chevrolet Impala and 1987 Oldsmobile Cutlass Supreme, will be showcased at a ceremony in San Francisco with a free event at the USPS facility.
