Here's another of the blank cards that are included with every set of our Happy Families card games. Just to be clear: You get a full set of Happy Families playing cards in every deck. It's just that you also get some blank ones that you can fool around with if you get the urge (totally optional - you can easily play without them).
Here's a Happy Families Playing Card created by a Clark family. The theme chosen for their family is "making a mess". Sounds authentic to us!
