Condition: 9/10

Screenprinted in 1991 by Liberty Graphics, this educational chart tee showcases natural history illustrator Diana Dee Tyler's detailed scientific renderings of marine mammals. Printed on a classic Made in U.S.A. Hanes Beefy-T blank, the garment features period-correct single-needle hem construction and a 99% cotton heather composition. Nature and marine biology chart tees from the early 1990s gained widespread popularity as environmental consciousness and eco-themed merchandise surged during the era. While many commercial wildlife shirts were printed in high volume, original first-edition 1991 Tyler prints in clean wearable condition remain consistently sought after by niche vintage collectors.
