Random photo – previous owner of the vintage album?

When I said my Great Grandmother was the first into the vintage album I wasn’t being completely honest. Hers was the first photo I put into the album, but when I got it (Ebay)there was a random photo in the front. I am very intrigued now about the origins of the album. Can anybody help me date the album or this photo? Even better would be some information about the people in the photo, but I think that is a long shot. I wonder why the rest of the album was left blank. There is some damage to the rest of the album so maybe other photos were removed. For whatever reason, I am pleased I have this little clue to its past.

They are not drinking tea in the photo, but they look like they would enjoy a cup so they can certainly stay where they are.
