 The cards are not arranged in suits, nor are they numbered (except for a tiny identification number beside the copyright line), so they do not lend themselves to games that are hierarchical or competitive, with winners and losers and scores.This aspect is underlined by the OH Etiquette (see below); a set of "rules" that deal more with behaviour, attitude, and communication skills than with legalistic boundaries.The OH genre grew slowly over the years, starting with the publication, in 1989, of Saga, a 55–card deck of paintings by Ely Raman illustrating scenes in possible fairy tales.
