Talkback indicator—commonly called a 'barber pole' due to its black-and-white stripes—for the Apollo Lunar Module, measuring 1.75″ x 1″ x .5″, sealed in its Grumman packaging with "Read Before Opening" tags.

Mounted on the instrument panels, 'barber pole' indicators were used to denote the status of various systems: when covered by a gray flag, the system was operating as normal; in the case of an abnormal or in-progress status, the flag would be actuated to reveal the 'barber pole' as a visual indicator.
