This is a cool piece of ephemera from Australia. If you were a good little boy or girl, and had a good checkup at the dentist, you'd get this nifty certificate with all the Wonderland character on it congratulating you on your dental diligence. Perhaps if my dentist has given these out when I was a child, I would have had better experiences in the chair. Live and learn :)
The list of characters is interesting - the Dormant Doormouse? Who's that? And what has the Mad Hatter been drinking, he looks like W.C. Fields!
