Great covers Paul, i remember buy some sets with that girl Clara, what a hottie! She made me take "work breaks" on various occasions;)
The thing about including photos is that you could have two different editions, one with PG pics and one with the uncensored pics, this way. Obviously if people are looking to shoot porn they should be looking at it and learning from it. Publishing the uncensored version might be a problem...don't know.
I wonder if the world is ready for porn coffee table books? Those oversized hardcover editions which are more pictorial, but with your history and the amount of material you have you could easily do a good one which would serve as a historical look at porn from the 80's and 90's as well. Just a thought. I think porn has crossed over into mainstream enough nowadays where younger people would buy that more than buy some "Better Homes And Gardens" coffee table book etc.
Hell my coffee table books are "Search And Destroy" about the 70's-80's punk rock scene so there ya go.
