Another Obama / Che Moment. Where Have We Seen T-Shirts Like This Before?

After church today, we ate lunch at a New York style pizzeria on Chain Bridge Road near I-66 in Vienna, VA. While enjoying a nice slice of pizza, I saw a woman come through the door with an Obama shirt similar to the one below.

Apparently, there's a shirt maker who has a whole stock of them.

Where have we seen this style of shirt before?

And that's not to mention the pro-Fidel Castro shirt I saw some idiot wearing at Whole Foods in Reston the other day.
