So a few years ago I had Troy make a blank for me for Iron Man 1 (Extemis), I had the intent to have somebody from Iron Man 3 sign it, and it just so happened that Ben Kingsley was obtainable of me at the Exodus premiere in the UK with help from a friend. Of course this wasn't witnessed, but due to the custom blank nature, the NG yellow label was acceptable for my OCD anyways, I then had artist Paul Shipper (his work is great if you haven't seen it before) sketch Kingsley as the Mandarin on it for me, which was of course witnessed. It was costly but I couldn't be happier!
Here it is:
Thanks for the blank Troy! It took a while to get it done (signed by Kinsley and sketched by the perfect artist for me) but great to finally make use of it
