I thought I'd include this profile of Wrightson, since it told me a number of things I didn't know:

It also has an exhaustive list of Wrightson's work, including comics and books.

Such as his involvement in THE SHADOW comic series, and why he ended up not being the series penciller he was promoted as.
There was a full-page house ad in KAMANDI 2 (Jan 1973) and other titles that month that made it appear Wrightson would be doing the series, and for reasons not clear at the time, that series went to Kaluta instead.

Sometime over the last year, I learned that his first wife, Michelle Wrightson, was previously underground comics artist Michelle Brand, and was a colorist for mainstream comics as Michelle Wrightson, mostly coloring Berni's work.
