Located just off the historic Howard University campus, this big and beautiful work is not really hidden, though there is additional mural work on the back of the building to enjoy while searching for the cache. The mural face is currently behind a fence, but the cache and close-up views are accessible by alley from 9th Street. The building owner has given permission for artists to work on his property, look for the mailbox holding samples of the owner's generous declaration.
The Washington Post writes:
This expansive wall shows a colorful procession of residents enjoying the city throughout the year. The improvisational style walks the viewer through a string of images evoking Mother Earth, Father Time, nature and cityscapes.
Please remember to replace just as found, and don't forget your writing utensil -- enjoy!
** Congrats to hutchjth for the rainy-day FTF! **
UPDATE: The Washington City Paper is doing a series of mural deconstructions they call Anatomy of a Mural; here's their breakdown of Seasons in the City by street-art nonprofit Albus Cavus' Peter Krsko.
