This is the shirt put out by Universal Studios in 1992 to promote their Bill and Ted Halloween Show.
The artwork has altered the usual Bill and Ted phone booth pose to include classic Universal movie monsters
peeking out, while the back includes a variety of Bill & Ted's catch phrases.

This baseball cap was also made available for sale at the 1992 Universal Studios Halloween Horror Nights
to promote the Bill & Ted wild west show.

The excellent ~J dude sent in these photos of the 2001 Halloween Horror Nights Bill & Ted t-shirt, although he says
they don't seem to have been selling any new shirts for the last few years!  Bogus!!!

The outstanding Zeldaartist sent us these photos of the 20th Halloween Horror Nights Bill & Ted t-shirt,
which are most bodacious indeed!  Thanks, babe!
