Overview

A pair of iconic underground comix posters featuring the 'Keep on Truckin' strut, a visual shorthand for 1970s resilience.

Story

Robert Crumb drew a one-page comic in 1968 that accidentally became the anthem for an entire generation. By the early 1970s, this image was everywhere—from the mudflaps of semi-trucks to the walls of every college dorm in America.

Maker / Origin

Robert Crumb is the 'Godfather of Underground Comix,' a man who transformed the medium from children's entertainment into a raw, often uncomfortable reflection of the human psyche.

Condition & Value

The posters show some visible waving and edge wear consistent with age. There appear to be some minor creases and potential mounting marks at the corners. Vintage posters in 'mint' condition command a significant premium, while these appear to be 'good' used examples.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

▲ Strong maker attribution with credible period details
▲ Better-than-average condition for the category
▲ Broader demand rises when presentation and finish feel intact

Concerns

▼ Decorative-only demand limits the ceiling
▼ Surface wear or missing provenance can compress the range fast
▼ Regional sale lanes often underperform specialist venues

Best Venue
