Artwork question here....Edouard Chimot prints circa 1925

Tweet

Recently I was going through some boxes I have from my grandparents. One of the magazines in it had some matted prints (cannot tell it is an actual charcoal sketch or if it is a replica). But it's really old looking. The date on the two prints by this artist is 1925. Now I really like the pieces but am curious as to whether they are collector items or not. So if anyone out there has any info other than wikipedia stuff...already checked that out. Hit me up with some clues here. Also there are a few prints in there by C. Gesmar...another artist from that era
