I bought a couple of these Aftershock patches off facebook last week.
Steve Sandt, who sold me these patches received them from Warped Sportz Chicago.

Earlier this year I bought the same style patch from Michael Karman, who played on the James Gang, Farside, Scream, Aftershock and currently Northwest Rogue.
Karman dated this patch to between 1991 and 1993.
Karman wrote about this style patch:
“The patch I sent you are the patches that got handed out.”
The team version of this patch has a slightly different tone of green as the background. The give away patches use a bright green and the team version is an OD green.
I recorded interviews videos with Michael back in September and they will be going online eventually.
