I’m including this because it turns up on internet searches, but I do not believe it is by Annie.
A watercolour, 735 x 535 mm (0.39 m²). Auctioned at Adam’s (James Adam and Sons Ltd), Dublin, 9 Mar 2014, in a job lot with total estimate €400-€600. Listed elsewhere as by Annie Swynnerton, by unlike her other works in medium, style, subject matter and colour palette. I believe this incorrectly labeled and not her work. www.blouinartsalesindex.com, www.adams.ie.
