If you are…take a picture, ask a question, anything! Whatever. Any comment you leave would be great.
I have no idea how busy the place will be. Even if you just go, get in, and get out, we’d love to hear from you.
If you actually have the chance, perhaps you could ask any of the following questions:
What is your favorite Tintin album, and, briefly, why?
What was your involvement, if any, with helping in the production of the last Tintin movie?
I wouldn’t expect him to have been involved, but you never know.
