Expanded Petty Gods is now out due to all the help of the old-school roleplaying community and the herculean effort by Richard LeBlanc of New Big Dragon Games. If you are not familiar with his stuff, you should definitely check out his website which is full of high quality old-school adventures and supplements.
You can download the Petty Gods pdf for free or get softcover or hardback books via print on demand at Lulu. See more at this link:
I contributed two illustrations to the project: Berenedril and Gilthigoet.
