I found the finale funny, but also touching and one of the most touching moments in the whole episode was the very end. At the very end of the episode (spoiler), Pam and Jim decide that they're moving and Pam, just before she leaves the office for the last time, takes her painting of the office building off the wall. So as I watched this all go down, I decided that her painting deserved a post. And here it is.
To start with, in The Office, over its many seasons, Pam's character changes dramatically. Whatever. But around Season 3, she decides she's going follow her dream and become an artist and she participates in an art show. So, in this episode, "Business School," she invites all the co-workers to her show and very few come. Oscar and a friend do come, but they criticize her work and it hurts her feelings. Sad.
Later, Michael comes to the show and he loves her collection of pleasant watercolors. So, he buys the one of the office building and hangs it up right next to the office. And when he does this, Pam gives him a big hug and is visibly touched and reassured, whilst the audience chokes back silent tears. Later, with all this confidence, she goes to art school and by the end of show, she reveals a mural of her coworkers. Just lovely.
To get technical for a while, the painting is a small watercolor. It is a simple painting of the office exterior and the parking lot. In actuality, the building is located in Van Nuys, California. Originally, the director did not like the paintings that the crew made for Pam. So, the crew had to redo them all. And I think, they looked pretty nice and really fit the character of a slightly amateur artist.
I loved this painting for many reasons. It's not an incredible painting and it contains no real humor. But, as Michael Scott once said, "there's a lot of beauty in ordinary things". More importantly, it creates this really touching Pam-Michael moment that really culminated in their sad farewell when Steve Carrell left the show.
Ironically, seasons later, the new receptionist Erin, ruins the painting during a non-existent "Pam-Erin feud." However, I think the writers decided to forget about it so that they could have this lovely visual of one of the best characters of the show, Pam physically taking something she created of the office, from the office, obviously symbolizing all the non-material things she took from her job at Dunder Mifflin.
