Any reason why there has been such a drastic change in his auto from the leaf releases to his newer topps ones?

Not to mention the newer topps autos don't look very much like his full signature from as recently as 2008 Super Super RARE Alistair Overeem Real Rookie Auto 18 | eBay
Odd that the same guy would go through 3 different variations on his signature in 4 years time.
