United States Liberty Stamp Album 1967 Edition Used With Stamps

Description

United States Liberty Stamp Album 1967 Edition Used With Stamps.
Lots of empty spaces but quite a few stamps.  Former owner I was told was a postal employee.
He added some inserts with blocks of unused stamps.  Some interesting envelopes with cancelled stamps.
Not sure what the penciled numbers are written under some of the stamps.  Stamps are both cancelled and not.
The stamps are mounted.  I pictured some of what I thought were interesting.  Please ask questions and I will be happy to answer.
Just know there are some great stamps for the collector.  Thanks for looking and HAPPY HUNTING.
