Getting Mail is SO fun!

Today I picked up the mail and mixed in with the bills, credit card offers, dentist appointment reminders and grocery store ads for grocery stores that are no where around here was a MYSTERY postcard!

I have no idea who it's from, but the handwriting on the address part (I cut it out of the picture so people wouldn't try to break into the apartment to get at Tyson's homemade corn bread) looks like a girl wrote it or a boy with very neat handwriting. My only other clue is that only a handful of people know that Tyson and I visited the downtown Seattle Library (the background of the card) earlier this month. Help me solve the mystery, tell me who sent the MYSTERY postcard.

I love getting FUN mail! Thank you MYSTERY writer.
