Thanks for "calling" ;)
The Brian is good, even though his signature at the time was mainly still the fuller signature you see in the late 80s, the 96 is a perfect example of his hand with numbers as well.
Roger is a bit odd, considering the Queen looks rushed, but he normally wouldn't draw Queen bubble letters unless he had the time to sit still and sign. However, it's still a good sig. I'd say it's just a rushed example. Normally Roger wouldn't do the Queen in bubbles letters unless a pretty lady asked for a signature, so it's likely that (rushed or not) Roger being the ladies man he is, drew it up anyway! Although I do believe it to be genuine, I would still suggest you wait for a better exmaple of his hand to become available. There are plenty out there with much more "handsome" QUEEN bubble letters he's done.
