Just to be a bit retentive here..
it should be noted most early callsigns didn't stand for anything when they were issued. Especially, three-letter calls; W calls with A, B, or C as the 3rd letter; and K calls with W, Y, or Z as the 3rd letter. Most of these were assigned sequentially by the Commerce Department.
Look at any of the early 1920s station listings on David Eduardo's site; you'll see large blocks of sequential calls.
Many of the slogans you read of for these early stations were invented by the stations (or by a contest of their audience) to match the callsign, not the other way around.
