Back (apologies for my handwriting!)
The text of the postcard is
Today, I will re-introduce myself.
My name is Brad, and I have a blog called DumbFunnery.com. It is full of silly things, like every Wednesday I have a picture of the postcard I have mailed you.
I do this (over 100 postcards plus a lot of other oddball posts) because:
1) I like to write silly things,
2) I hope to one day write silly things at a professional level (i.e. get paid),
3) Maybe you would read a postcard and invite me to talk one day.
