This pin was given to attendees at the 1st (1992) Disneyana Convention at the Walt Disney World Resort. It came on a EuroDisney mouse-ears backing card, priced at 35ff, so it must have also been for sale the opening year of the park. The pin features Mickey finishing up his painting of the "EuroDisney" heading on the pin and the line underneath the name. It's very similar with pin 1241. I think this one is smaller and the paintbrush is here yellow and red in pics 1241.
