Nearly 15 years ago, when I started lugging my Canon AE1 with me everywhere I went and taking photos of whatever caught my eye, I started looking at building I'd seen all my life as if for the first time--and noticing details I never knew existed.
Example: I'd gone to the tiny library on Chicago Avenue in Ukrainian Village for as long as I could walk, but until I started snapping shots here, there and everywhere, I never noticed the terra cotta child's face framed with bat wings--yes, that's what they are--along the top edge of the building.
On Easter Sunday, I passed the site where the library had been--and found it empty.
No library. No child with bat's wings. Nothing but crushed rubble.
