Today several signs were mounted in and outside of the museum. Something interesting was discovered while mounting a Bell Telephone Company of Pennsylvania sign.
The old 1964 Bell System logo was covered with the 1969 Bell System logo. The replacement 1969 Bell System logo has now been mounted above the sign. You can see the mounting holes in the sign were the replacement logo was mounted. It must have been a lot cheaper to create covers for the old logo than create more signs.
The sign is a very heavy one that has been cast in bronze.
