Actually Pumpkin, it is unusual that they’re a year apart and the signature is almost identical. That is what makes it stand out. Look at one of your signatures from a year ago - then find something you signed recently. Are they nearly identical?
What, exactly, are you implying, if not that it was copied? BTW, yes, I can find old signatures of mine that look very similar, actually all will look very similar, and probably quite a few that are nearly identical.
