Thickhead by Scotty Ulrich is a free groovy display font with a soft, heavy bounce that feels straight out of late-60s poster lettering. The letters swell into rounded, blobby forms with deep dips, stubby joins, and a loose hand-drawn rhythm, so the whole font reads playful, gooey, and a little bit cheeky.
It fits music flyers, record sleeves, retro branding, kids' packaging, and magazine cover lines where you want a bold word or two to carry the mood. As a free font, Thickhead works best in short display settings, title cards, and logo-style lettering, because those plush shapes and exaggerated curves do the talking fast.
