Would you believe: headgear around the world. Hats tiny and ENORMOUS, hats of skin and felt, hats for protection against the weather, against food contamination, bees, falling objects; the ""special hats"" of nurses, sailors, and policemen. ""Gandhi caps"" and mortar boards (""Hats for School and Clubs""), the Pope's miter, a Sikh turban; football helmets and stocking caps (""Hats for Sports""); a Swedish girl crowned as Santa Lucia, cowboy-hatted kids at a rodeo in Australia (""Hats for Festivities""). Some cross-cultural implications, some intriguing intimations of difference--but this is more the kind of exhibit a child would benefit from making than one to ingest ready-made. Especially with questions like ""Can you think of other special kinds of hats?"" propping it up.
