About Nightmare Weekend

Nightmare Weekend, presented by GalaxyCon, blends the high-energy fandom of eerie with the uncanny pulse of horror culture. By merging voice actors, screenings, cosplay competitions, panels, and celebrity guests from the world of horror, it redefines what a nightmare show can be. For the creepier side of fandom, mark your calendars for a weekend full of horror and spooky fun for everyone!

JSA on-site services for autographed memorabilia

Submit autographed memorabilia for Basic Certification (COA), and items are processed and finalized the same day. Collectors can also submit items for the JSA Letter of Authenticity (LOA). These are observed the same day, with final documented results sent later by mail. Go to SpenceLOA.com/fees for submission pricing.
