Vintage 1940's Palm Beach Cafe Mid Century Modern Menu

This original menu, believed to be from the 1940's, has prices that will blow your mind!
T-Bone or Filet Mignon $3.50, a crab cocktail 60 cents, Jumbo crab legs $1.80, can you imagine? The menu is fragile but the colors are still very vibrant, I had it in a frame for years.
There's a stain on the back cover and a small stain on the front, I haven't attempted cleaning.
The restaurant was an Oregon Coastal Restaurant called the Palm Beach Cafe, the menu is signed by Dave Babbitt and measures 10" X 13"
