I have thoroughly studied Stan and Steve Ditko's signatures throughout the years and I am almost certain this is not any good. The "s" is far too enclosed within itself, and the double "e" at the end is a wretched mockery of a forgery.  Of course, "This above all: to thine own self be true" But if it were me I would say a certain no. But once again, that is just my own opinion, I could be wrong. Hopefully it turns out well for you at the end, and I hope you the best with them/
