i apologize i put this in the wrong spot yesterday , but i need some help if anyone knows about a painter who signed his work J S a********( the asterisks represent the faded portion of signature ) it is done in red the capital J has the S centered over the J like you do on a $ sign and next to that is lowercase a acompanied by the faded portion and the whole signature is underscored by two lines the right half is too badly faded to read
thanks in advance and sorry for my earlier mistake of putting this in the wrong place first time - best regards goo
