Seeking examples of postcards for off market deals

I'm looking at relocating to another city and purchasing a property for myself and my kids. My plan is to purchase a property that needs renos to force the appreciation that way.

I'm looking for examples of post-cards that I could use to drop in mailboxes in the neighbourhoods I'm interested in. I'm looking for something a little more than the traditional yellow letter campaign and thinking of using a pic of me and my kids. Good idea? Bad idea? Thoughts? Help?
