Weekly Photo Challenge: Philadelphia Patterns

(Actually, I’m not sure whether the “patterns” challenge is still open or not. My computer was unusable for a couple of days, and I’ve barely started to go through my backlog of email. But even if there’s a newer topic by now, at least I can come up with a post on this subject after missing half a week – so here goes.)

I photographed these patterns in Philadelphia last summer, but each of them is only a small piece of the original picture. Can you guess what the real subject was?

Pattern 1

Pattern 2

Pattern 3

Pattern 4

And here you are – the uncropped photos:

A bus shelter

An apartment building

A church door

A fountain in Rittenhouse Square
