Bart Simpson Pins.

These are not date stamped so may not be official Simpsons merchandise.

Two of the pins have what appears to look like a bit of enamel on the back (see pic) Doesn't affect the front of the pins in anyway. This was done in the manufacturing process.

I got these in Barcelona in the mid 90's so they are quite old now. There are no marks, scratches etc on the pins. Picture shows a lot of reflection.

They have never been worn so are still in excellent condition.
