At a local estate sale, I recently came upon four framed vintage prints.  I looked at them and instantly fell in love with them.  The only problem was was that I have no idea who could have made them.

They look to be famous Scotsmen, and they are professionally framed and matted.  To me, the illustrations themselves look like they could have come from a book.

They also appear to have a CURRIER AND IVES look to them.

I have not been able to track down any information about the artist and who could have printed them.

Does anyone know who could have done these great prints?  Any information is greatly appreciated!
