As I recall, the orange sections were really more pink... and all of the colors were more flourescent, rather than just bright (although not glow-in-the-dark).

So, yeah. I bought the shirt at the 4/28/1988 Austin show (at The Ritz), opening for Butthole Surfers. Second time I ever saw them, and second night in a row - after the 4/27 Houston show (at Numbers). They were so ridiculously loud back then!
Another one I wore a bunch was my Butthole Surfers shirt, based around the 1st image in this collection of LSD sheet art. Definitely got that one at a later show - possibly The Ensemble on 12/9? The octopus was screened in thick black ink over an orange field, with BUTTHOLE above and SURFERS below.

I liked to wear it to Grateful Dead shows in the late-'80s/early-'90s. It was a big hit!
And just in case you doubted nary a word of what I've told, I now produce evidence!
There it is!! Funny, I don't remember ever noticing the right edge being so distorted. My perception during this era might not have been entirely reliable...
Bonus pix: This was my usual go-to Dead shirt around the same time period - fairly generic, but it got the job done.
