Hello,
Don't know if you can help me trace a portrait in oils painted by Joseph Thomas Steadman between 1888 and 1889. His sitter was James Maybrick, a Liverpool cotton broker, which (according to a press report) was executed at the artist's Liverpool studio shortly before Maybrick's death in May 1889, allegedly the result of being poisoned by his young American wife. The press critic found it an "excellent likeness and very fine picture" which was exhibited at the Liver Sketching Club's exhibition in June 1889.
Regret unable to shed any light on the link to the Onions family, but any information about JTS's picture of Maybrick would be gratefully received.
