Graphical Analysis of the Fed Balance Sheet

I was reading Ben Bernanke's speech a couple of days ago (you can read it here: Fed's Exit Strategy) and I really began to wonder what the Federal Reserve's balance sheet looked like. Well, here it is... kind of.

The breakdown of the assets are posted below in two graphics. It doesn't show the Fed's liabilities, but those are straight-forward enough (i.e. money deposited to banks).

I would have just posted the table, but that's not as fun as looking at these and trying to figure them out :)
