Unknown, but so familiar

I found this letter on the floor of a room in my house a few years ago. I think it must have fallen out of an old book. Where the book might have come from, I'm not sure. It reminds me of the nostalgia associated with "Mad Men." Letterhead (on the navy trimmed beige stationery) reads Mrs. Frederick A. Sanford, 75 Tennyson Street, West Roxbury, Mass. No idea who that was.

Marie, darling:
What kind of a run-around are you giving us? If you don't let go pretty soon Uncle Fred is going to call the doctor for me as he swears I am going to have the baby instead of you.
It is a darn shame you are having such a 3-ring circus and not even a clown or two to cheer you up, but it will soon be over I am sure and you will forget all about it. At least you are getting a bit of rest, I hope, and not scrubbing that kitchen floor.
I told Lyman I didn't wonder he couldn't raise flowers in your back yard if he planted them as deeply as he evidently does his baby.
I had a nice talk with Wayne on the 'phone and told him if he was a good boy and minded his Nana Uncle Fred and I will buy him something special. He was all right although keyed up a bit, but he laughed and talked with me quite a while.
We are without a car for a day as Mitch had a slight accident Sunday. Turning in to the church at the curb he bumped into the bumper of another car and while he didn't even scratch the other car, it put a big dent in the fender of our car, so we are having it fixed. You can imagine how glad I was that Mitch was driving and not Uncle Fred.
We are very busy as usual. Two more weddings lined up for June and corsages galore for high school "Proms." Just wait until Wayne gets into high school and you and Lyman have to pay for corsages for the lady-love!
I went in town yesterday and bought some new slip-covers for our living room furniture. The others I had won't fit now that the furniture has been re-done. They are rather good looking and I hope will look well on the furniture.
I wore my new suit last Sunday (and nearly baked) and everyone said I was quite the belle of the ball. I am anxious for you to see it.
Well, dear, I don't want to tire you, so will quit this time, but hope you'll soon let go as every time the telephone rings, I have "nervous prostitution."
All my love, dear, and Uncle Fred and Mitch say "Me, too"
Affectionately, Auntie
