We should be doing this for all articles of clothing in those paintings. Seems like there is a timeline. Young girls in pool/shower room, some end up in woods, or swamp. (Large estates have this) then the old lady with red wall paper background has different time period shirt. Then it looks like sea-can's which potentially contain…something? Out of the ordinary unless macabre for the artist. If the time period can be identified by looking at cranes, railroad buildings, model sea-can then potentially can determine when the Stadium was built, cross reference with Stadiums in that time period then do building layout in surrounding area as comparison to find whatever location she was referring to. Could be nothing…could be something.
