I don't believe this is Ms. Granahan's signature. There are certain aspects that remain constant in handwriting unless a person deliberately tries to change it. If you'll notice the "yn" in "Kathryn", the roundness of the "y" as it flows into the "n" is absent in the handwritten signature. This would not be common for someone to suddenly change to a pointed "n". Also, the "y" doesn't contain a loop in the handwritten signature as it does in the actual signature. The pointedness of the "y" into the "n" is the main focus of authenticity due to the fact that it doesn't maintain the "flow" of the actual signature. Additionally, the crossing flourish on the "t" in "Kathryn" barely extends to the first loop in the "y", whereas in the actual signature, the flourish exends nearly to the end of "Kathryn". Regardless of the size of someone's signature, rarely does the "aspect" change. Normally, if someone crosses a "t", it remains somewhat constant no matter how they sign their signature. The "y" in "O'Hay" contains two loops in the actual signature whereas the handrwritten signature contains no loops at all. The last "n" in "Granahan" ends as an upsweep. The handwritten signature doesn't. Normally, a stylized signature such as Ms. Granahan's will usually contain the stylized features regardless of how many signatures she was signing at one time. Fatigue will show in signatures, but rarely will stylization change. Personally, I think someone had been practicing Ms. Granahan's signature, felt as though they had finally gotten it right, and signed the bill. Signatures can, and do, change over the course of time. Assuming this is, indeed, Ms. Granahan's signature, it could depend on WHEN the bill was signed. Without further documents to compare, I think this signature is suspect.
I'm jumping on the "it's real" bandwagon.Sign your own name two or three times and you'll see major inconsistencies in each one.I'm one of those people who USED to practice forging other people's signatures for fun and was pretty good at it.I specialized in my parents and it got me out of school a few times as a kid.I could never have duplicated one as closely as on this note without tracing.
The only why your signature is going to look the same everytime is if you use a rubber stamp. I've looked at several bills like this one being sold online and my opinion is this signature is authentic.
I think it's really her signature. Try this, Sign your signature ten times, then look for minute differences between the first signature and the last one. There will be more differences than you would think. In this case, she was probably sitting someplace signing souvenirs for awhile. No two will be identical to the "perfect one" that is printed on the bill. It doesnt sound logical to me that someopne would sit around practicing a duplication of her signature just to put it on the bill. It looks authentic to me but you should have it checked out. Bill
