We are thrilled to announce that our friend Coop, famous rock poster illustrator and fine artist, is joining us at our Weekend of Wonder extravaganza, September 18-20 in Riverside, California.

Coop is creating a special illustration for the event, and our sponsors, Prints on Wood, are going to make a limited-edition print (on wood!) for every attendee. Coop will sign each print and hand them out during the event. He will also hang out during the weekend to chat and enjoy the activities and performances with the everyone else.

(Note: the image show here is a different print Coop made. The one he is doing for Weekend of Wonder will be new.)

One of the activities during the weekend will be a visit to the Prints on Wood facility in Riverside, CA, where we will see how these prints are made.

The Coop print is just one of many pretty darn amazing goodies that Weekend of Wonder attendees will be given at the event.

We are super excited about Weekend of Wonder. It takes place in about a month. We anticipate a sellout (but it won't be crowded – it's going to be like a happy mutant family reunion), so of you want to come, I suggest you register soon!
