This is not a parody. The artist who created the stencil image discusses it here.

It is inspired by the Shepard Fairey posters, discussed earlier here.

UPDATE: All kinds of odd Obama fan posters out there.

For example, until now, I had no idea Obama is a drawer from which doves and butterflies will be released.

Nor did I know that Obama is also, apparently, a 1950s detergent.

There’s a joke about Obama being transparent in there, but I’m not touching it…
