The origin of the phrase is uncertain, but it was first heard in the 1930s in jazz music. “Keep on truckin'” is a phrase of encouragement that means to keep going or persisting with something. The logo was also adopted by counterculture bands like the Grateful Dead and Phish, and it has become a symbol of the counterculture movement of the 1960s and 1970s. The Keep On Truckin’ logo is made up of a variety of different colors, such as maroon, silver, black, and purple. The phrase “Keep on Truckin” was also used on posters, patches, buttons, and bumper stickers and became a popular motivational message. The comic and its catchphrase, “Keep On Truckin,” quickly became popular among hippies and were much imitated and displayed during the hippie era. The logo was created by artist Robert Crumb in the early 1970s and was featured in his underground comic book, “Zap Comix.” The comic strip was a visual burlesque of the lyrics of the Blind Boy Fuller song “Truckin’ My Blues Away,” which featured an assortment of men drawn in Crumb’s distinctive style, strutting confidently across various landscapes. The Keep On Truckin logo features a man on the move, one arm extended and the other holding a cane or a stick.
