[MassHistPres] Mass GIS historic data

[Ermmwwt at aol.com]

This looks like an interesting topic, but I do not understand what I ought  
to be able to see in the attachment.  To me it looks like a scan of part of 
 a vintage map, and I don't see any GIS data.  Is there something I  should 
be looking for?
