Under normal circumstances, ordinary ticket holders of comic-con exhibitions can ask guests to sign their names. However, the specific signing opportunities may be different according to the different exhibition and guests. Some guests may need to sign in the infield, and some guests may provide signature service directly on the spot. Therefore, if you want to get the signature of the guest at the comic exhibition, you'd better know the relevant activity arrangement and guest information first, so as to get the signature smoothly.
