Free Photoshop grunge brushes created by Thia @ Hybrid Genesis in 2011. There are 6 brushes in this set, all of them are larger than 2000px (a big file). They are suitable for web as well as print work. She created them in Photoshop CS3 and also included the stamps (.jpg images) of the brushes in the zip file for anyone who doesn’t use Photoshop or using the earlier versions. Please credit Hybrid Genesis, not me.
