Hippies loved t-shirts - especially ones with pot and sexual references on them.
Even the freakin' company's name (Roach Studios) sounds like the punchline to a "Share a Little Tea with Goldie" sketch.
I've always felt these types of shirts look interesting when grouped together, but are slightly less effective when seen individually. ("Makin' Bacon"...? Jeez.)
The details are hard to see in this scan, but clicking the image gives you a bigger picture.
