Hey Annie , remember?

I think its the 1940's. It could be early 40's too, looking at the waved hair of the ladies in the back. That fashion, I believe, was left over from the 1920's and perhaps worn also in the thirties. The apron's look very 40's and the dresses at the back with spots are 1930's fashions.
I remember a relative having a dark green dress liike that with a frill round the bottom, and loose frilly flaps on the sleeves. The spots were grey/cream and looked like eyeballs . It was like one spot overlayed on top of another . She called the colour "bottle green". I know when the spots fashion came out because she told me she had bought it in the thirties but hardly worn it as she was not fond of the colour.
Looks like a Christmas tea for the local seniors, to me .
