Snap.
I bought up a few display cards from a shop closing down as well MX 250, and in there was them little ones too, what I found was i could sell them onto jet ski riders, PWC etc and some boats need them small ones too cause they have a few numbers in the rego to display and there the right size
Also donated some to the Pee wee kids so they could use them on Demo ride days and getting ont othe spirti of racing about and they love em.
Also back cowl of some street race class bikes used em as well.
hope that helps with ideas.... otherwise you'll be fitting em on your lawn mower.
