Polo Brush by Richard William Mueller is a free brush script font with a loose, hand-painted swing. The letters have thick, inky strokes, tall upright forms, and playful round turns that make the style feel casual and slightly retro, more sign painter than neat calligraphy.
It fits naturally in posters, cafe branding, album sleeves, shop signs, and event flyers where a quick human mark feels more right than a tidy script. As a free font, it also works well for short headlines, title cards, and monogram-like initials, because the broad brush shapes and open rhythm give even a few letters plenty of character.
