Agathe from eternal-kate.net just sent me this:
“As you already know, Kate will receive an Honorary César, February 24, in Paris. Me and other fans will be there that day and we would like to offer her a little gift: a poster with pictures of her fans wearing a hat.
To congratulate Kate for her honorary César, we would like to offer her a poster collecting pictures of her fans wearing a hat. To participate, please send me a picture of you wearing a hat, at this e-mail address: email@example.com. You have until February 16 to participate. Then we will offer the poster to Kate during the César, February 24. We hope many of you will participate!”
Well, what are you waiting for? Submit your pictures! :D
