The Autographs and Photo-Ops at Anime Matsuri are divided in two categories.
These Guests have booths in the Exhibit Hall and are available to meet fans for extended periods of time (usually during operating hours of the Exhibit Hall). For this type of session, you can pay directly at the Guest’s booth
These Guests do not have their own booths. Their Autographs and/or Photo-ops are scheduled and access to them are only done through pre-purchased tickets. These Autograph/photo-op tickets are usually available about 2-3 months before the convention.
