Are you there, Karl?

I received this from a Grandpa named Karl, who gave no information as to how he came to send it to me.  I can't find him on SwapBot or Post-Crossing.  Karl, if you're there, please drop me an e-mail to basykes@dcn.org and identify yourself...and thank you for the cute card!

Guys, I am so behind on posting income and outgoing mail.  I really do hope to get caught up.  Someday!
