my thinking of this show grew out of an exhibition called the stein collect which is gertrude stein and her siblings, americans who went to paris during the first years of the 20th century. matisse and me cast owe before they were household names. sarah stein which was richard stein's sist in law owned a number so there's one painting in the show called young sailor which was owned by sarah stein. and we know that when matisse painted it he also painted another version of it. he brought them both back to paris and showed them to gertrude stein's slightly older brother and showed him. and they talked about it. so this idea of pairss one is in -- owned by the statin museum. there are partners on this exhibition and that was really and that was really another genesis. it's not an exhibition about pairs though it's an exhibition about progression. he painted in pairs since the mission of world war i. it's less this idea of comparison but about process and repeated images. >> rose: what does this exhibition show about his evolution as a painter. >> it was clear from the first paintings 17899
