Trading Yokes!

Update from my previous post :  I was so so excited when I received a letter from the White House last night.  I didn't expect that I would get another respond from them, since I have already gotten their email.  This time the letter is typed but our President Obama signed for it.  So I would like to share my joy with you.  What should I do with the letter?  Is it worth to frame it?  What do you think?  :) Did you see the seal?
