The background is a chalkboard, and the marks are indeed on it. they show up in the print as was intended.
You can get a vector copy if you'd like, and replace the background with whatever you'd like. Just PM me with your email address again requesting it and I'll get it out to you.
So, I've sent the file to 64 unique email addresses, so hopefully this cool looking sign will be adorning lots of game room walls in the future. Post pictures in this thread when you've got your done and up, maybe?
Also, I had a couple of bounces. If you haven't received the file you asked for, let me know again and we'll work out another arrangement for getting it to you.
