Description

Celebrate with a little old-school charm in this vintage-inspired graphic tee. The artwork features illustrated party guests gathered around a playful “BIRTHDAY HAPPY” banner, rendered in a mid-century palette of muted red, teal, mustard, and cream. Its slightly offbeat wording and retro character make it feel like a found illustration from a well-loved greeting card.

Built on the heavyweight Gildan 5000 crewneck, this unisex T-shirt has a classic, easy fit and substantial 100% cotton feel. The artwork is printed with crisp color designed to hold up through regular wear.

  • Heavyweight 5.3 oz cotton crewneck
  • Classic unisex fit with a relaxed everyday shape
  • Made to order and shipped worldwide with free standard shipping

Each piece is produced after your order is placed, helping us avoid excess inventory and create only what is needed.
