It would seem the garbage can art at the top of the page is straight theft except that the details are so different. Maybe they're both based on another older drawing that went around on paper, maybe in the early days of photocopies when so much "office humor" was exchanged that way (though these aren't humorous).
These with the gun coming out though, aren't as similar. If anyone knows any history of these or has other examples please write to me at [email protected]
