New York is filled with scamps and scoundrels, perverts and pranksters, so when Brooklyn-via-Denver musician Travis Egedy, also known as Pictureplane, discovered a poster taped to a subway wall with a pinch of weed attached, he had to wonder: Could this gift be for real? And more importantly, should he smoke it?

Turns out, Egedy wasn't the only one who made such a discovery this week:

@TheGardenBreath A big thank you from my buddy who's visiting NY, Peace from across the pond :) pic.twitter.com/h4GJtO30ze — Billy Wright (@CheltBilly87) October 17, 2013

Because this is 2013 and even a magical pot fairy needs a social-media presence, the anonymous benefactor left a Twitter handle that, until today, had sent out two messages:

These are tough times. Keep your spirits high. — The Garden Breath (@TheGardenBreath) October 12, 2013

As long as we're this high up, we can't be brought down. — The Garden Breath (@TheGardenBreath) October 13, 2013

But then this morning, two more updates appeared, one insisting the gesture isn't a marketing ploy and another identifying the cannabis strain:

I'm not promoting anything. I just want all of you to feel good. — The Garden Breath (@TheGardenBreath) October 18, 2013

In case any of you were wondering, the strain that you're smoking is called Kushage. — The Garden Breath (@TheGardenBreath) October 18, 2013

For the record, the Garden Breath doesn't seem to be a product or a brand and the United States Patent and Trademark Office database doesn't turn up any trademarks or pending applications with the name. So who could possibly be behind these random acts of kindbudness?

As it happens, we may already have the answer. Spoiler alert: It's not Banksy.
