I have that same 91 GTP model... complete and un-assembled in the box... although the box for mine has some major water damage rippling going on. Means I got the model for a great price though.
I love the metallic blue color they molded the parts in... it might even be the same color as my Grand Prix

I also have the "Car of the year" model kit... that can be built 2 ways.
Although it was started, screwed up and abandoned when I got it. It looks like most of the pieces are there... enough to build a complete model out of anyway. I just gotta figure out how to strip the old & badly applied paint off several of the pieces before I can start building.
Within the next few weeks I will also have the Don Keefe book, I am looking forward to reading it! I have a copy of the 1994 Pontiac dealer showroom catalog coming in the mail too.
Not really sure if any of this counts as memorabilia or not, but I have the 1994 Grand Prix Factory Service Manual (both volumes)... a copy of the OEM parts catalog on Microfiche... and by tomorrow I'll have a Tech-1A
