@Sturgis,
The '50s porn I was referring to was porn of old Disney characters. There's probably porn of other old cartoon characters from the '50s.
There's probably cartoon porn made that's even older.
I remember when I was in grade school or middle school some boys were drawing Transformers porn. They didn't draw robots engaging in sexual acts, they were drawing robots having "discharges", which to me is/was disturbing and gay.
Transformers was a popular cartoon series from around that time.
When I was in high school I remember there was a boy drawing naughty pics of Cleo from
The Catillac Cats.
I used to draw fan art of cartoon characters when I was in public school, from grade school to high school, and even in art college, but nothing I drew was pornographic or fringed on being pornographic.
This was before commercialized internet access came about.
Around the time I first started using the internet I discovered that artists were making porn out of a lot of old '80s and '90s TV cartoons and animated films. And out of some old Hollywood cartoons.
I wasn't intentionally looking this stuff up. I used to be a big cartoon nerd or geek I was searching for SFW stuff. I was also looking up indie cartoonists and animators. Eric Schwartz was one of the earliest online animators and cartoonists I learned about - the guy who created Amy the Squirrel and Sabrina the Skunk and other characters. He's an underground artist - I'm not going to go into his work.
When I was in art school I was working at a local supermarket. A young man I was working with knew I was going to school for animation and he knew I was influenced by Looney Tunes cartoons. He told me I should make "Looney sex". I looked at the boy like he was crazy and told him "no." He looked at me and said, "Then you must not be interested in making money."
I told the boy I was a Christian and that I'm not making cartoon porn.
I remember one time on my way to or from art school in NYC I was on a bus doodling in a sketchpad and I drew a male anthropomorphic cat standing around being surrounded by a bunch of sexy-looking female anthropomorphic cats. This was one of these things I drew to see if I could. I remember there were older ladies sitting around me and they looked at me disdainfully when they saw what I drew. They must have been Christians. I felt ashamed and I think I scrapped that drawing. A young college boy shouldn't be drawing stuff like that especially if he is a Christian.
I don't draw cartoon smut.
