How many unsigned Grannies prints are there?+

Does a Grannies need a Pest Control certificate?+

The major auction houses only offer Banksy prints with a certificate from Pest Control Office, the artist's authentication body. Without one, a print cannot be sold through them, and the results here will not reflect its value.
