There are many ways to buy tickets for comic exhibition, and it is no problem to buy them on the spot. Sometimes changing tickets in advance is slower than buying tickets on the spot ... I learned it yesterday.

You don't have a notebook. You only sell original comics or novels.

If signing means that the author personally queues up to sign, many organizers want you to buy it at the exhibition, otherwise you are not qualified ... I don't know if it is all like this, cicf is like this ... you don't need to bring any gifts to the author specially. If you are qualified, you may be asked to find a staff member or a signing place near a specific service shop to collect signature tickets.

Take your schoolbag. If you want to buy a lot of things, you should carry it comfortably.

Because I don't know how long it will take you to drive, I suggest you go earlier and around eight o'clock.
