Opinion on Drazen Petrovic Auto?

[nicker10]

Just curious if anybody has any opinions on this Drazen Petrovic autograph. Thinking about possibly purchasing but not positive on authenticity.

It looks like the one I got from him through the mail, but he signed mine on the back of the card. Not sure if that's the norm or if he just did that for me, or what.
