This is a mural painted on the stairway wall leading to the Hamilton Methodist Church on Waller Street, home to the Haight Ashbury Food Program.
The dedication (located near the top of the stair post) reads: 'I wish to thank Judy Woods "She made sure even angels had shoes". - rja.' The painting is signed by R. J. Allison.
The Judy Woods referred to is a former graduate of the food program's job training program who ran HAFP for 14 years. She was let go early in 2008 before the program itself closed its doors in April due to lack of funding. (link)
