In 1965, kids could buy book covers for their favorite NFL team, such as this cover for the Baltimore Colts:
Here is a closer look at the front (note the $.10 price in the upper right corner):
and here is a closer look at the back showing helmets for all the NFL teams (note at this time helmets were shown with chin straps):
Here are the other teams I have been able to find pictures for with this design:
Chicago Bears:
Cleveland Browns:
New York Giants:
Detroit Lions:
Washington Redskins:
There was also a cover showing all 14 NFL Helmets and Team Logos:
Here is a closer look at the team logos:
The book covers could be purchased in a group of 5 for $.49:
In 1966, the design changed as seen on this Green Bay Packers book cover:
and there were now 15 teams with the addition of the Atlanta Falcons:
which is also reflected on the back of each book cover with the team logos:
Here are the other teams I have been able to find with this design:
Chicago Bears:
Dallas Cowboys:
Detroit Lions:
Los Angeles Rams:
Minnesota Vikings:
New York Giants:
Philadelphia Eagles:
Pittsburgh Steelers:
Saint Louis Cardinals:
San Francisco 49ers:
Once again, the book covers were available through an offer on 1966 Philadelphia Football Card Wrappers, but the offer now includes 16 covers for $1.60:
The same design was used in 1967 as there is also a book cover of the expansion New Orleans Saints, but note that the back cover still only shows the 15 teams that were in the league in 1966:
It appears they used the same design in 1967 (which is why these are sometimes identified as being from 1967), but didn't bother to update the back to include the Saints.
The book covers were again available through an offer on the 1967 Philadelphia Football Card Wrappers:
There were also AFL book covers with a similar design
but the backs had the team logos in a shield:
It looks like these were available in 1964 given the copyright:
To wrap up, here is another item which would have been great to have heading back to school back in the day - an NFL Folder:
This folder has a 1967 NFL Properties copyright:
