A close up of the signs on the wall and also the ticket booth window.
The next picture is of the rarely seen Dumbo ticket booth. This booth is also in action as well. Check out the signs not only the big sign, but also the cool little shield sign.
I can see why a ticket book made more sense, less cast members are needed to person each ticket booth for each attraction. All the tickets for Fantasyland attractions can be purchased from one booth instead of multiple booths. Eventually even land ticket booths were not required as guests would buy a multi ticket book at the front entrance and use the tickets as needed. Of course, tickets also spread guests throughout the park riding various levels of rides, instead of everyone waiting in line for that E ticket ride.
