Martha Werre was my great grandmother Lydia's younger sister. Martha was born in 1898; Lydia was born in 1896. Martha and Lydia seemed to have a close relationship and loved one another, based on letters and postcards. But, it seems no one really disliked Lydia. She had many people who adored her.
This postcard was written in January of 1949. It appears Martha was visiting LA for some reason, but it may have been purely for leisure. Lydia was a widow at this time, as my great-grandfather passed away in October of 1948. Martha probably wanted to visit with her sister since she was now alone (my Grandmother, being the youngest, was married and living away from home).
