I would not sell my collection, for if I did, i would cry (Part 94)....

 Today In The History Of Polt's Comic Book Collection

Today we travel by 38 years to October 1985 and DC's Crisis On Infinite Earth's #7, and this iconic cover. 

As the cover shows, this is the issue where Supergirl dies fighting The Anti-Monitor (at least until she comes back in a rebooted history several years later).   The cover is by The Maestro George Perez, and again, just LOOK at the detail in the background!  Despite there being so many people there, and it all being dark, every one of them are distinctive and can be identified. 

This cover has been copied a LOT over the years, but none have surpassed this original one.
