My two favorites would be a Jackie related photo and press pass that serve as a nice bookend.
My first ever photo back in 2016 was Jackie signing with Montreal in 1945. I then added a pic of Branch Rickey signing with the Dodgers in 1942. What I wanted to complete the set was a photo of Jackie signing with the Dodgers in 1945 alongside Branch Rickey. This year I got it. The image is blurry as heck in the PSA slab. Thinking of liberating it. But it is sharp and a beauty. PSA calls it a Type II, RMY gave a Vintage 1 window for it. It don't care either way!
Then my first World Series press pass--a sweaty 1956 pass covering Jackie's last official game.
Honorable mention to Kershaw's first win ticket.
