A small headcanon of mine that before he went to Azkaban, Sirius raided what was left of the Potter residence (small trinkets from James and Lily) and kept them in a box to one day give to Harry. Never having the chance
After he dies, and Harry Ron and Hermione come to Grimmauld Place on their search for horcruxes, Harry finds an old t-shirt of Sirius’s along with…a box. In it is his mom’s old Walkman! Everyone always headcanon’s Sirius to be obsessed with muggle bands and what not, but I like to think that a certain muggleborn witch introduced him, and he kept this from her.
