Identified as: Mr. H. W. SIEGFRIED
Photographer: Alfred Harmany Studio, Lancaster PA, circa 1870
Purchased: Feb 2024 Palm Beach County Fairgrounds Antiques Show
The inscription on reverse says "Mr. H. W. Siegfried, Burtsborrow, Berks Co., PA"
I suspect the location may have more accurately been Birdsboro, PA, a southeast suburb of Reading.
The photographer, Alfred Harmany, operated a studio in Lancaster from 1863-1875, at which point he sold the business to F W Willig. So the photo can certainly be dated to between those years. Fashion makes me think around 1870.
With only initials to work with, I cannot be certain which of several H. Siegfrieds in the area this was.
