Exhibitors at Comic-Con must provide show management with a CDTFA-410-D swap meet, flea market, or special events certification. If you will be conducting selling during the event you must also provide a valid CA Permanent/Temporary Seller’s Permit. If you set up without a valid CDTFA-410-D form or provide Comic-Con with an invalid number, all fines incurred will be passed on to you, the exhibitor.
