It would be nice, but I doubt LEO's would care what's in a flyer if they're having a problem with your OC. My attorney suggested carrying $150 for bail when I OC, so that's my "flyer."
Either the LEO's would recognize the legality of OC or they won't. If they do, then "no problemo," if they aren't aware of the legality, then plan on getting booked and let your lawyer argue the legality for you.
The Hamdan decision is a bit long to put into a flyer, so maybe carry a page from the Wisconsin Constitution containing Article I, Section 25 (with the helpful annotations)plus your lawyers phone number.
