While rummaging through some junk that they were throwing out of the design lab (Yeah I rummage through the trash for free supplies), I came across a brochure from 1981 for perspective templates.
I figured I would bring them into the 21st century. So I scanned the samples that were in the brochure cleaned them up and now voila. Perspective brushes. There are 30 in all. I'll be releasing them in packs of 10 as I do them.
A note on perspective:
These are meant as a time saving tool. You should really learn how to handle perspective on paper first, so you understand the concept fully.
