At the symposium of the Committee for Museology, ICOM (ICOFOM), held in Zagreb in 1985, the author raised several questions connected with the theme of the symposium, Originals and Reproductions. The questions referred to the number of copies of a work of art, particularly of sculpture. At the Art Conference held in Vienna in 1960 international rules and standards were set, but most of them are not observed by Yugoslav museums and galleries. The standards require that the artist should determine the number of casts, the type of material to be used, and that each cast/copy should be provided with a number. The conclusions of experts at the ICOFOM symposium were: (1) the gallery or museum which has the original or the model in its custody has the right to copy or cast it, after the object has been assessed from the scholarly, sociological and economic point of view; (2) the value of the original in situ should be kept and not reproduced; (3) beside these principles particular regard should be given to ethics and the observation of the agreements reached. -- AATA
