DPS school artwork and logos

Now that plenty of our historic schools have left us, is there a shop or store at DPS or any of the schools that still sell sportswear? I am looking for vintage [[1978-1982) t shirts, sweatshirts and gear from elementary, middle and high schools... most of the websites offering have updated things, but I need an original 'Guest Middle School' Cougars t shirt with the cougar logo, and also Renaissance HS logo with the winged Phoenix from the late '70s to early '80s.

And what about the defunct schools like Redford, and [[soon to be) Western HS. Should I just contact the athletic depts at the respective schools, or should I contact DPS administration for historical details or artwork? It would be a great legacy gift.
