Mr Jarvis, also Mayor of the Sheffield City Region, unveiled the new work by Barnsley artist Liz Grundy at Emmanuel Methodist Church.
It depicts First World War ‘Tommy’ and a short Act of Remembrance was observed following its unveiling.
The two-foot tall sculpture, a private commission for an ex-serviceman, has been carved from Portland Stone and finished with details including a stainless steel rifle and brass buttons supplied by Nicholas Hoyland of Penistone Engineering.
