24 Hours on 2nd Avenue

In NYC's East village at East 7th Street and 2nd Avenue. I took a picture of the other side, which was lit better, but it was blurry.

Sustainable NYC

I found a penny in front of this place on Avenue A across from Tompkins Square Park. I did the green thing and reused it.

Brooklyn, New York

Near the offices of Energy Hub.

Honourable Mention

Strictly speaking this sign doesn't qualify because we are looking for circular signs that display front and back but it's on a motorcycle from Isle of Wight so we'll post it.

I'm waiting to here from the person who submitted these two images from the Isle of Wight and, with permission, I will post the submitter's name and a link if available.

Post from the Isle of Wight, UK

I received two submissions from Mel in the UK today. This one bends the rules because it is not a circle, it's more of an oval shape, but hey, it's from the Isle of Wight so it's cool!

I think I might have to relax the rules a little bit because I firmly believe that round signs (circular, to be precise) are a sign of economic boon. Folks, we're about to square up.
