Rube Goldberg Sex Machine Cartoons? [Moved]

[Freddo]

I'm looking for the name of the adult magazine from the late 70's or 80's that used to print Rube Goldberg type cartoons except the machines were sex machines. For example a hampster runs on a treadmill which turns a gear that makes a dildo go up and down and a girl sits on it.

Here's a pic of an actual Rube Goldberg cartoon so you get the idea of what I'm talking about. They used to print one of these every month I think. I thought maybe it was Playboy, but I can't find these cartoons anywhere. The artist's name or any other info would be a great help.

Sorry if this is in the wrong section, but I couldn't find an appropriate place for this request, thought this might be the best place. Thanks for any help.
