Morning Task, The

A rather dark study, by an artist whose signature I have not yet managed to identify which, because of its colours became surprisingly challenging to assemble. The box reference number of 2194 is not unique to this puzzle, appearing in various other examples of the era.
Please let me know if you can help with an artist’s identification. I will be very glad to update the record. Thank you.
