There’s a club for that!
The #dc-pride club has a history of readings of queer representation from DC- you can check out their Club Room here, or jump straight to the list of all topics devoted to DC Pride here.
We also have a collection on DCUI of curated selections you can find here.
Like @TurokSonOfStone1950 said, keep your eyes peeled for a full month of events covering representation throughout DC’s history, both characters and creators 
The Club Leaders have been hard at work compiling the most complete database possible, and it’s turning out beautifully.
