The Signals series is an inquiry into the relationship between words with deep cultural connotations and the maritime signal flags that represent the letters of the word.
The International Code of Signals flags are used to signal between two ships or between ship and shore. The flags include 26 square flags which depict the letters of the alphabet. In addition to representing a letter, each flag also communicates a message.
L = you should stop instantly O = man overboard V = require assistance E = altering course to starboard
P = about to sail E = altering course to starboard A = keep clear C = yes E = altering course to starboard
