1. Retrieve Pickman's gift
I saved the killer Pickman, and to thank me, he gave me a key to the safe in his gallery.
Don't forget to grab the Lock Picking Bobblehead and the Astoudingly Awesome Tales magazine from the ground.
Use a nearby ladder to go outside, go back to the gallery through the front door and find the picture "Picnic for Stanley".
