Vulgar Display, by Digital Graphic Labs, is a retro free display font with the chunky, cut-paper attitude of late 1960s and 1970s poster lettering. The letters feel broad and blunt, mixing big rounded curves with abrupt angled cuts that give the font a slightly unruly, hand-shaped rhythm.
It makes sense on album covers, poster titles, magazine cover lines, storefront graphics, and short packaging names where a free font with this much period flavor can do the heavy lifting fast. Use it when you want a headline or title card to feel bold and a little offbeat, because the caps have enough swing and asymmetry to carry very few words on their own.
