The newest incarnation of the restaurant & bar space at1407 14th Ave is called Bar Sue. The mural in front of the bar is definitely an homage to the seventh volume of the Adventures of Tintin, called The Black Island.
The mural shows several Seattle iconic signs and objects awash in seawater. I guess it could be seawater that had swept over the city from a tsunami .. or the elevated sea levels from Earth’s melting ice caps.
Some signs are from beloved businesses that had closed years ago, and others are from places that are very much still around.
