I have a card like that which I keep in my wallet. It's the same size as my driver's license and folds in half, so it actually has four sides. The first explains that I have autism and what some of my symptoms might be, the second explains how the person I'm showing it to can help me, the third has my parents' phone numbers as emergency contacts, and the fourth just has a small descriptive paragraph about the basics of what autism means.
Other people sell similar cards online, so I'm sure people would have an interest in yours. I like the yes/no feature, that's unique and I haven't seen it before. To be honest though, I just looked at the cards being sold online as a reference, then created my own for free.
