I have a CD made by "HI-Tech Software" "Firebird ads from the beginning - 1967 - 2002" that features all (just about every one they could find I imagine) from the first ones all the way up the the new birds... you download it onto your computer and have a spreadsheet of all the ads, and can preview in thumbnails and open full size images from there... I also have the GTO version... "GTO Anthology" You can then print out any you want for display or what ever you need... Got them off Amazon.
It was cheap, and I thought pretty cool. Just FYI if anyone needs a specific ad etc...
