These three dumpsters sit at the entrance to Doc's on 12th Street. The one that looks like wood is not. It's been skillfully painted to look like wood. I believe the artist is Jo Brown, whose murals I've shown in earlier posts, and who painted an outstanding mural on the back of the Sears store across from this dumpster. To the left of the dumpster is the River Walk, and to the right is the bank of the Columbia River. The red-topped cans are for recycling.
There was a famous Astoria painted dumpster at the 6th Street Pier when I arrived here in 2001, but it's gone now. It was a fanciful painting by Diane Beeston showing sea creatures and a dancing octopus. I have a photo somewhere and will post it when I find it.
For those who asked about the rooftop garden mural, yes, it is a mural. There are a number of roof-level murals in Astoria, and I'll get their photos taken one of these days :)
