Does anyone remember an animated movie about a Christmas tree that never got sold and over the years grew too big finally it was chosen to be in Washington or New york?

You're likely thinking of the 1974 animated special "The Little Christmas Tree".

Here's a summary:

* The Story: A small Christmas tree, named Rusty, is overlooked at the tree lot year after year. He grows bigger and bigger but is never chosen because he's not perfect. Finally, he's chosen to be the official Christmas tree for the White House in Washington, D.C.

* The Characters: Rusty, the little Christmas tree, is the main character. He's joined by various other Christmas tree characters and the people who choose him.

* Themes: The special explores themes of perseverance, believing in yourself, and finding your purpose.

While it's not a widely known movie, it's a sweet story about the spirit of Christmas and the joy of unexpected journeys.
