American Headstone

A recent aquisition from America was a glass plate negative of a grave in an unknown cemetery. I estimate it to date from about 1900 and made a scan from it this evening. The name John E. Gibbs can clearly be read on the headstone which looks brand new. A sign to the left of the stone has the letters NB above VFA on it. Perhaps that means something to North American students of funerary architecture? Fascinatingly, a small plaque to the right reads 'Perpetual Care'. I wonder if the headstone has been crafted from Vermont Marble? I am intrigued by the white stone borders which seem to separate the plots as far as the eye can see. Comments are most welcome!
