Of all the said Banksys popping up nationwide lately, Banksy has confirmed a few, including the Battleship Potemkin stroller in Chicago, “I remember when all this was trees” in Detroit, the sunbathing Osama in San Francisco and “You concrete me.” A few more pieces were spotted in Detroit and Toronto. See the recent confirmed and yet-to-be confirmed Banksys below.

After gardening illegal ads into “Poster Pocket Plants,” artist Sean Martindale continues creating public art, albeit with permission. The Toronto-based artist recently spent 24-hours threading a “Free” installation in the city’s Grange Park, sanctioned by the Art Gallery of Ontario.

Pieces of string, tied 44-feet between chainlink fences, outline Martindale’s letter piece which is planned to last until “the city’s squirrels and birds chew away the string for their nests. |Torontoist|

I assume the homeless in Toronto are treated a lot like they are in New York City: Unless they’re willing to sing, tell a joke, or perform some other act of public embarrassment, they’re virtually nonexistent—except if the Satoralist finds then fashionably relevant. But not everyone is talented, so street artist Fauxreel launched a guerrilla PR campaign to humanize these poor Canadian vagabonds as part of his “Unaddressed” series. Some samples above and the full set here.

Combining guerilla gardening and illegal ad takeovers, two Toronto artists cut and fold billboard and flyer ads into planters.

After planting some trashed newspaper dispensers with flowers and herbs, Posterchild is looking at what the city of Toronto is sowing. Instead of foliage, weeds, trash, even more trash, banana peels and “nada” are filling the city planters that Posterchild carefully cataloged. With the small signs, the guerilla gardening street artist hopes to inspire others to claim these misused spaces and at the minimum “discourage people from planting anymore garbage trees.” |Blade Diary|

In addition to sanctifying subway advertising, Toronto-based street artist Posterchild does guerrilla gardening too. He posted some new photos of his latest project: flower planters built inside trashed and mostly unused distribution boxes for crappy free papers no one wants. Sadly, the flowers don’t last long.

Why? I can’t say. I suspect that the box-owners are enforcing their territory, making rounds or complaints, maybe claims of safety issues. Who knows? But I hope that they were taken by garden-loving individuals who were excited for the possibility of free planters, soil, or plants….That’s a much nicer thought than the whole thing being pitched on principle.

Posterchild laments that while the foliage is quickly cleared away, the trash and empty sidewalk-hogging newspaper dispensers are near cleaned up. Click the images above for a lush look at the “green graffiti.”
