Here is a 'real photo' postcard, I would guess from
the first half of C20. On the original postcard, there is a white
border around the photo.
The photographer appears to have written his company
name (Donnelly Photos) and the postcard number (466) on the negative.
The company name has been written in the lower-left
corner, and the postcard number has been written, for some reason, in the
middle of the field!
I don't know where this photographer was based, and
don't know of any other postcards by this company.
