NOTE: The icons that go with the initials are all the same except for GS and AGB which have an identical icon.

shouldn't GS be George Stephenson - 1814 or 1825 - since the image is of the steam locomotive? - Rainaer

angelushack: answer: triton

wabbit24: The San Francisco picture shows 3 items above the same starburst(?) pattern: A locomotive (invented by George Stevenson/GS), a telephone (invented by Alexander Graham Bell/AGB); both represented in the mural. The only one not represented is the statue of Poseidon, who's son is TRITON.

Triton is the name of the largest moon of Neptune (the planets in the Berlin projection end at Neptune). Neptune is the Roman name for Poseidon (Greek).

Triton - was also the Allied "code name" for a communication network using the Enigma machine. Also it is used by several companies for different products and systems like

  - The code name of a popular Intel mainboard chipset in the mid-1990s
  - The name of an internal project at eBay used to manage the company's Pay per click keyword portfolios

Athena = Missile

Poseidon = Missile

Triton = missile

Triton (a merman), Princess Ariel's father in the Disney animated film The Little Mermaid. Possible connection with the Murmuring Rock (mermaids singing) </spoiler>
