OMG, it’s not even the same color ink.
This is as bad as the Rather Typewriter.
I’m wondering if the black and blue ink effect is more an artifact of the scan than evidence of two pens. The “Moore” does appear to resemble other Moore signatures. But the whole thing could be a forgery.
I was just going to say; If you’re going to lie, keep it simple. If you start getting elaborate, forging evidence, and giving specific details, you better be very good at what you do.
