Mid Century, circa late 1920’s-early 1930’s original charcoal drawings. These are all fantastic life drawing studies and done very tastefully. Unframed and looks to be signed 'mack' by the artist, who at this time is unknown to me. They may be European, since I found a paper watermarked ‘France’ and there is a lightly penciled name that looks to be French.This measures 19w x 24h and can be framed inexpensively with a simple black frame available usually in any department store that sells picture and document frames. This is a fairly standard size. From a pet and smoke free home.
