Another Plea for help...

and I must beg forgiveness. Last week I received a bubble mailer in my snailbox with a nice assortment of Phillies for my collection, along with a few cards off of my 07 Opening Day wantlist. But I have NO idea who the sender is.

The return address is Redhook Ny, with Joe's Dog Training on the label. I would love to know who Joe is, and if I owe him anything in return for this awesome little surprise.
Thanks Joe,
Please enlighten me.
Have a GReat weekend!
