When Jim transfers to the Stamford Branch he sites a promotion and that "you can’t beat that view” as his reasons for leaving Scranton. Directly behind Jim (behind Karen’s desk) a poster can be seen with text reading “WINDOW OF OPPORTUNITY”, accompanied by a picture of a window with a nice view.
During the first conference room meeting we see Jim having at the Stamford Branch, he can be seen sitting along the edge of the room, next to the door, and beside him sits a woman with an almost identical hair style and color as Pam.
On the monthly calendar behind Angela's desk we can see an event on the 19th that says “Sale Group Meeting Lunch”. The location is listed as “Jim’s Diner”.
