Seamen's Bethel, 1881
This wonderful old sign suffered the same fate as Forbidden City; on August 14, 2006 it was painted over in black and an easily-updated vinyl poster installed over the top.
"Drink Coca-Cola" covered the original "California Lodging House" sign. Coke's "Delicious and Refreshing" slogan dates to about 1904 according to several web sites, making the sign a little over 100 years old when it disappeared.
Note on the next-door building (foreground) another partial "Delicious and Refreshing," still visible.
Look south from the corner of NW 3rd and Everett to see this.
