Bestetti and Tumminelli, later C Chierichetti, Milan
Operated 1913-1924 by Emilio Bestetti and Calogero Tumminelli as a publisher of art books and this series of art postcards. Some cards just use the logo and some (eg 585 below) give details of the publisher.
Later cards carry the name C Chierichetti. The last example shows that Chierichetti eventually changed the logo from Ars Minima but added AM to the card number.
