On the IL Camaro site they actually list the event your car was in as part of there history.

"February, 1992
The club is invited by the Chevrolet Division of GM, to attend a press conference on Friday prior to the opening of the 1992 Chicago Auto Show. We are to help celebrate the 25th Anniversary of the Camaro; 35 members attend. We are treated to hors d'oeuvres and Jim Perkins, manager of Chevrolet, speaks to us. We are interviewed for a Chevy Video magazine. Some members are interviewed by WMAQ-TV, channel 5, which is then aired on the 6 p.m. news."
I would try and contact Rory Smith. The tresurer would like the photo for the club records and to share on there site.
