What is "raree show"

"peep show contained in a box," 1680s, so called "in imitation of the foreign way of pronouncing rare show" [Johnson]. "Johnson's statement is prob. correct; the early exhibitors of peep-shows appear to have been usually Savoyards, from whom the form was no doubt adopted" [OED]. Early "peep shows" were more innocent than what usually was meant later by that word.

n. 1 A portable puppet show or picture show as used for public entertainment; a peepshow. (from 17th c.) 2 A public spectacle, especially seen as lurid or vulgar. (from 17th c.)
