»La gorra del presidente

A colleague accosted me today and said: "You. You like hats. Try this one on." And indeed, the hat looked lovingly handmade, and felt wonderfully soft. I wore it the rest of the day and received many compliments.
"My mom sent it to me, but I've got a melon head" he said by way of explanation.

Apropos of explanation, skullphone goes a little way to clearing up how I've seen these awesome wheatpasted posters in San Francisco and London (don't have a photo of the latter, sorry).
