As far as basic form it is not as "inventive" as some of the nonsense out there, there are some genuine that approach this "style" - but this is no good. There can be no date, there can be a skip or pen left esp by or to the paraph, but this is all too curvy and smooth - first third of the "B" says a lot. Some spatial relations and size relations also pose problems.
Then there is something like this - PSA, R.E.A.L. & RR cert as well - but what would you do with it? I could never suggest it to a customer.
This OP "signature" roughly translates, in "Bowiespeak", to "Boo". It is SO heavy on the right side not even a date would help (and what date?). Like some bad Shatner efforts ("Bill"), not understanding what is done and why provides the reveal without much effort from our vantage at all.
If you erasedsome, add a curl back here, straightened another bit out, and added a slight angle over there out you might fool some, some of the time. But...
