Now, are we looking for a signal we can use just walking by someone on the streets? Or someone we are standing in discussion with? That we see on the bus? Are we looking for a sign we can send to parents, asking them if their kid is diagnosed? When we spot someone hanging back at the fringes?
The scenario where we would be in a position to ask / toss a sign seems to be sometime where we're already (at least half) certain someone has an ASD...
I would think it's got to be someone that you've seen/know somewhat, not just a random stranger. I'm not sure that making secret gestures to parents about their children is a good idea!

Maybe we'd be better off with a "token" than a physical sign?
A little rubber WP alien on our keychains / necklace to pull out in query?
This is an idea I've been thinking about before - something subtle and discrete to display that would strike a chord with an aspie, but be uninteresting to most people - but I searched for little aliens on keychains and didn't find any, not even a WP one. So I thought about a diy version, based on the 'green person' idea which crops up in some images using 'people-pawns'. In fact, since little green plastic people-pawns for games are quite cheap, you could just give one to someone, and ask "Ever feel like you're an odd-one-out / on the wrong planet?", and see if they take it further.
I also like the rainbow infinity ∞ symbol for an image which would work well on a business card or similar item, although so would a green person/alien image.
Painted (apple?) green with a screwed-in attachment loop. For a keychain or a zip-pull on a bag. The actual shape/size could vary somewhat. And it could even have an expression if wanted.

The Green Stranger Network - perhaps memes would do the rest.
