Question - how was their no dust on the table that was set? Maybe I just can see in the picture, but wouldn't the glasses and plates have a covering of dust by now?
If its been abandoned for over 50 yrs, no dust on the table setting makes me think that was one fastidious lady who wasn't going to let dust be on her table! Death would not stop her war on dust
Ladies of that era had a really different approach to housekeeping and appearances. That house, abandoned or not, is cleaner than a lot of people's houses I know!
