Yesterday I posted pics of Union Jack by Bowen Designs. You can't have Union Jack without Baron Blood. This bust was released in 2006, sculpted by Mark Newman.
All that's missing from this set is a 'Spitfire' bust.
The most recent incarnation of Baron Blood was the grand-nephew of the original Baron Blood, and son of Spitfire. It's complicated, but there's been three Baron Blood's, only two of them connected to Union Jack & Spitfire, the second one being Victor Strange, who was Dr. Strange's brother.
