New signature T-shirts

Sometimes a random thought comes into my head. Like the other day. Don't know why. Don't know how. But it ended up on this kids T-shirt. Call it a mess. Call it a scribble. I like to think of it as a random signature.

Do you think every signature is unique? Like a fingerprint? I doubt it somehow. Does this look like your signature?

Either way, our 9 year old now has one of these and all her friends want one.

PS Comes on baseball jerseys and hoodies too.
