H&M Herringbone Cap, size 2-4 mos.
We bought it for 300 yen in Japan and absolutely loved it--he wore it for a day or two only
Last seen: As we left the house for lunch at Pixar on 1/27/11; mother packed it to show off baby only to lose it somewhere in the car, restaurant or parking lot. Never seen and sold out at every location. (We have seen two other babies in San Francisco with the hat - we covet it still).
