Space 1999 Signed Brian Johnson Helmet limited edition of 13 of 100.  Obviously very rare and long unavailable as these were scooped up by collectors very quickly.

This is the Brian Johnson signed edition helmet not to be confused with the picture on the box which is the standard packaging.  Unlike the other helmets offered by Sixteen 12, this is a unique product.  It was the only SIGNED helmet.

The plaque inside and shown in the photo shows its 13  of 50. The box says its 13 of 100.   

The item has never been displayed. BRAND NEW - Definitely BNIB.
