These are two tiny cards from Gary's dressing room congratulating him on the success of his play 'Lease'. Both cards are hand-signed on the inside- The first one says 'Gary: We Love You!' and is signed Minnesota and Tennessee. The second one says 'Way to go Gary!' (not sure who it's signed by, looks like it starts with an 'S').

Here's where they are, hiding in the background in his dressing room.
(The second circle is just brightened up so you can see them.)
