20 Grunge Brushes, made in Photoshop CS, compiled into one .ABR file in Photoshop CS.
*UPDATE* File is now a .zip with two .ABR files, one for Adobe Photoshop 7.0 and one for Adobe Photoshop CS. Grunge on!!!
Please note me if you use them. Some sort of credit would be nice as well, but is not required.
