Once upon a time, Steven Rotblatt started Rubber Chicken Cards, working with a few good freinds who had unique and odd talents. They wanted to make humorous greeting cards with quirky cartoon characters. Over the years voice actors and award-winning artists joined Steven to conjure more then 100 hilarious characters. We work hard to make sure our cards are the funniest and most relevant cards on the market. It takes more than 40 hours for our talented teams to give each card it's special brand of silliness.
