I would think that autographs ordered from Englund's own website would be pretty solidly legit, and the prices are certainly reasonable. That being said, I can't really vouch for the quality of the photos/autographs in contrast to any other signings he may have done.
Thanks Richard, I was just checking to see if anyone knew for sure whether or not it was HIS site and not something operated by a proxy or a fansite.... I do have an update for you though.... I wrote this last night as I was anxiously awaiting the return of an item I sent out to Robert for signing. I'm alwayw worried doing things through the mail etc. ANYWAY... I just got the item back and it was signed. My anxiety is gone. Thanks for the help..
