Running Extravagant, Vladimir Nikolic's free striped groovy display font, channels late-60s and 70s poster lettering through dense parallel lines and soft rounded turns. The letters feel continuous and almost tubular, with the stripes doing most of the styling while the broad arches and open inner shapes keep the rhythm easy and bold.
It fits music posters, retro branding, event flyers, packaging, and magazine cover lines where a headline needs a swinging, graphic pulse. As a free font, it also makes sense for title cards, short logos, and monograms, since the line-built forms give even a few letters that unmistakable period flavor.
