The difference being the number of the item. This is labeled BG084 which is the number assigned by production to keep the mask cataloged and paired to the background actor it belonged to. The lens has some scratching from production.
I have pictured it from every angle. It is a blow mold with a plastic printed covering and a leather strap.It's actually a very clever design. This does not come with a studio COA, however, I will provide a COA from Wookiedesigns with the item which has been researched and verified as having been used in the production of "Suicide Squad". I can verify this item as being made by production but please do your own due diligence before purchasing. These items can often be picture matched if screen used or they often come with wardrobe/costume tag identifiers.
Com/memorabilia for more screen used props!
