I am not familiar with this term. I will take a stab and assume you are referring to small, portable exhibits which teachers or others may check out of the museum and take home. If so, you may want to contact Dan Brinkmeier at the Harris Loan Extension at the Field Museum of Natural History, Chicago. (312-922-9410) They've been doing this since the 1920s, if not longer. On a tangentially related note, didn't Marcel Duchamp smuggle miniature versions of his "greatest hits" across Nazi-occupied France in a valise, while posing as a cheese salesman? That latter piece may be an embellishment, but I have seen such a valise at the Art Institute of Chicago. Eugene Dillenburg Lead Developer, Philippines Coral Reef exhibit John G.
