All of the photos are snaps stuck onto card album pages which are loose, the first 2 photos are on the same page, the third photo (yesterday's picture) is on a different page, but believed to be the same holiday which is in France/Germany/Austria - I'm not entirely sure of their itinery.
Although the pages are loose, they have been 'sorted' according to the type of album page, photos and handwriting (as well as same people).
Today's picture is on another of the pages, and this one is of their visit to Stratford on Avon (birthplace of Shakespeare).
So this may be her . . .
