I think it really depends on the celeb and how much time they have. For example, some folks receive replies really quickly, like 5-6 days. With some celebs, months will go by and suddenly you'll see a bunch of success all at once. On those, I'd guess they wait and do them all in batches.

We are not agents of these celebrities, so nobody can tell you this. Ask celebrities themselves lol

Hi, so I had a question concerning the Celebrities signing autographs:
When do they sign or do they have a specific time where they sit down and just sign autographs?
Not talking out Pre-print but an authentic auto. Do they just sign really fast and leave or do they sit at their house or what ever and have a time of day where they just sign fan-mail?
Just wondering

Thanks guys
