Bride with a swooping veil

This is a 6 x 8.5 inch photo, undated and unidentified. On the one hand, there’s a lot of detail to look at, in the face and head dress, and especially the bouquet with all the fancy trimming. But on the other hand, the overall impression of the great curved streak of white against the empty sepia background is one that is almost plainly geometric. However you view it, I think it’s quite pretty.

Beautiful. Her bouquet appears to be Lily of the valley.
I think you’re right. Funny coincidence, but after posting this last night, I continued a non-fiction book I was reading, and got to a description of a wedding in 1929 that featured a lilies of the valley bouquet.
