I think it's fake.
It looks like the counterfeiter has used the autograph from Roger Taylor in Killer Queen (Mick Rock book) as an example to fake this one.
Does not look convincing... but I would not say it is ABSOLUTELY fake though...
It is not realy very clear enough due to the bad quality scan...
Some shapes are okay, though it looks like one that has been 'drawn' instead of put quickly as an auto should be.
In any case: if this pic is all that the seller provides, I would definately not bid on it.
