I'll take a brief detour from baseball, and post one of my favorite returns: Alex Morgan, the forward on the US Olympic women's soccer team. She was part of the team that won the gold medal at the 2012 London Olympics.
I sent this one in January 2014, and it came back the following August. I'm not sure why she used two different color sharpies, but no complaints here. I sent it to the address for the Portland Thorns FC, for who she is currently playing.
