What is the name of this style of graphic design that I see on T-shirts and posters: https://i2.wp.com/davidnunezdev.wpengine.com/content/images/wordpress/2015/02/ax0276gr-website-templates-4templates.com_.jpg?w=960

It’s a very loopy calligraphic-looking effect. Quite a bit organic and bold, usually monochromatic. I’m calling it Calligraphy Weeds until someone tells me otherwise.
