So the question is this.... So can you tell me if this looks like your signature or maybe know for a fact this is your signature?  I have this hanging on my wall in my home for family and friends to see but every time I look at it, I wonder is it even real?

Answer: This looks like the Heroland Gold Signature Edition.  There is another Heroland Platinum Edition (signed in silver ink) as well, which came with a numbered certificate of authenticity.   The Gold signature may or may not come with a letter of authenticity, according to mycomicshop.com (although the letter, itself, indicated that every signed book came with a letter).

Profits from both Heroland Editions were donated to combat Juvenile Diabetes. Limited to 3,500.
