Yesterday I received an actually book seller catalog in the mail. I can't recall the last time I received a physical catalog.
The one I received yesterday has a few tidbits in it.
I don't have many old mailers, but I will look through what I have and post what I believe to be interesting King related items (not 20 pages, just a few tidbits).
Hopefully others can post some interesting things.
EDIT: For large and multiple images PLEASE use the spoiler tag preceded with a brief description of the contents.
It will speed page loading and likely be appreciated.
For now:
