Look for ink distribution. If the ink seems uniformed throughout, then obviously it is stamped. Look for Pen pressure and also flip the letter and see if there are indentations on the other side of the signature, that is also a good indication that it was signed.
I don't know this signature but that lacks the grace I expect, it looks drawn and those ""ll's" seem wrong. The "R" construction has precedence? Take this with a lot lot of salt! Sorry if this only muddles things. Others will know FAR more, of course.
