Downy parachute

This is the seed of a milkweed, several different species of which are found in Brooklyn Bridge Park. According to this site, it’s a parachute seed, one of seven different wind-dispersal types.A framed version that I found down the block. Looks homemade, using the same techniques my old stained glass artist of a roommate used. It’s etched in the corner “K2K.” A gift from someone to someone else (?) who then let it loose in the metaphorically winds of the sidewalk bazaar.
