These guys only existed for a few hours. Where Spencer Alley gives out onto 16th Street there are tempting surfaces for boys with wide-tip markers eager to commit felony vandalism. There is also a zealous restaurant owner who polices the area with his pots of touch-up paint every morning and eradicates whatever went up the night before. Consequently, any photographs have to be taken promptly and early because there will be no second chance.
I took my creature pictures very early on Saturday when I was going in and out of my building (through the battered gates pictured above) to do laundry down the street and around the corner.
