As Superman is my favourite superhero, if I could only choose one item of my collection to save, it would be this. The certificates were produced by the Superman Museum of Metropolis in Illinois and hand signed by the creators of the Man of Steel, the legendary Joe Shuster, Jerry Siegel and also Kirk Alyn, the first screen live-action Superman. I was so thrilled when I saw it framed I told the guys at World of Superheroes that every Superman fan would want one of these so they did a deal through an intermediary and bought out the remaining stock. Includes an authentication certificate from The Sterling Collection signed by Steve Eyre | Includes a COA
