UPDATES!

UPDATE: 22 October 2026:

Trish and I couldn’t be more excited to officially announce our new GNO Militaria Show in Biloxi, Mississippi! Our good friends Terry and Gary handed us the reigns of the long running Gulf Coast Military Collectors & Antique Arms Show and it is now going to be our GNO Militaria Show: Biloxi, or simply our “Biloxi Show.” It will be under the umbrella of GNO Militaria Shows, LLC and will be a 100+ table event. We are currently working on the exact number of tables the venue can support with the best dealer and visitor friendly layout. A lot of excitement is continuing to build around this show and tables are selling out fast. In regard to the Greater New Orleans Militaria Show in Mandeville, from now on it will ALWAYS be the FIRST full weekend in OCTOBER! So, you can now plan well in advance and never have to miss the GNOMS! The new Biloxi Show is locked in to ALWAYS be the weekend before labor day in May. We are going to do all we can to change the way military antique shows operate and usher in a new era of militaria related events. We have a lot to do to make this happen, but we are already well underway to hosting shows like no other in the nation. Thank you all and if you need anything or have any questions, please do not hesitate to contact us at any time!
