Mat Collishaw - Children of a Lesser God - seen here
I hope I get a chance to see this show at the Foundling Museum in London, it's on until 9 May. The museum memorialises Britain's first home for abandoned children. These three artists have not shown together before, but their themes and subject matter sit particularly well in this context. The Museum has a history of working with artists to highlight the plight of vulnerable children and mothers begun by William Hogarth in the 18th Century.
Here's a Guardian video about the show.
