Sign by the Gemini EVA umbilical. It reads

Umbilical Cable: Tether

Astronaut Ed White performed the first U.S. EVA (extravehicular activity), lasting 20 minutes, from Gemini 4 in 1965. He was secured to the spacecraft by a 25 ft gold plated umbilical cable which also connected the suit to the on-board communications and life-support systems. The hand-held self-maneuvering unit in his right hand helped him control his movements.

The original Gemini 4 post-EVA mission plan called for Ed White to reopen the spacecraft's hatch after disconnecting the umbilical and re-connecting his suit directly to the spacecraft's environmental control system to jettison the EVA equipment, but since he encountered difficulties closing the hatch after his EVA, the jettison procedure was scrubbed.
