Gibb photograph archive, Volume 2
No. 18f - Janet Longhorne(?)
Unknown location. The print is within a long sequence of cathedral-related photgraphs, so the people shown here are probably also from that context.
The monument looks like the same one as in photographs on page 32. The context of that photograph suggests this is a Longhorne family visit, with Gibb, to the place. Perhaps the lady sitting on the monument is consequently also Janet Longhorne.
The man and woman to the rear left, may be part of this party, and also Langhornes, but could also just be others visiting the place at this time.
