I have two autographs from Howard Stern, and I'm wondering if anyone has an opinion on them.

The first was signed in 1997. Howard added his "Hey Now" catchphrase on top. Next to the "97", there's a second signature from a comedian who happened to be on Howard's show that day.

If anyone knows Howard's signature well, I'd love your opinion. Thanks so much!
