I'm getting ready to make a mailer to send out to prospecitve clients, but I'm having complete artist's block. I've decided to start a group on Flickr for other artists/illustrators/designers to post photos of their promotional materials. I figured that if I'm having artist's block when it comes to this stuff, there are others looking to break into the business dealing with the same hurdles.
So, if you're an artist/illustrator/designer and would be interested in sharing some images of your past and present marking materials, please join the Flickr group "Illustrator & Designer Marketing Materials" at http://www.flickr.com/groups/idmm/.
