I-90 PA Metric (Pennsylvania) Road Sign T-Shirt - Design
This t-shirt showcases a design inspired by the I-90 PA Metric road signs from the brief U.S. metric experiment of the 1970s and 80s. The artwork directly references the visual language of American interstate highway signage, offering a nostalgic nod to a unique period in transportation history.
Artwork Elements
The central element is the iconic Interstate 90 shield. It features the standard design: a red banner with "INTERSTATE" in white lettering, a blue field bearing the prominent white numerals "90," and a white border. This signifies the major east-west route connecting Erie, Pennsylvania, with neighboring states.
The design may also incorporate a "PENNSYLVANIA" text or banner, which sometimes appeared on older versions of the state's signage, above or below the shield. A directional banner, indicating "EAST" or "WEST," might also be included, further emphasizing the route's purpose.
Meaning and Symbolism
The I-90 shield immediately evokes the Interstate Highway System, a symbol of American mobility and infrastructure. The metric context adds another layer of meaning. It represents a specific historical experiment with metric units in the United States, a period of transition that eventually faded. Therefore, this design celebrates a piece of transportation history that is unique to the U.S. highway system.
The design, while rooted in practicality and information, transforms the familiar road sign into a graphic statement that signifies a specific time and location: Pennsylvania's stretch of I-90 during the metric era. This gives the graphic a special kind of collectibility, especially for those that remember the metric era.
