Thanks for all the C&Cs on 'Hagoday'.
This grotesque is on the porch of the Guild chapel, one of Stratford’s best-known buildings. Situated on the corner of Chapel Lane and Church Street, it overlooks the site of New Place, Shakespeare’s Stratford home, in which he died, in April 1616.
The chapel was largely built in the fifteenth century, as the chapel for the Guild of the Holy Cross, which was later suppressed by King Henry VIII. This grotesque is later though (post-1948), as evidenced by the polo mint on his tongue (I never thought I would use a polo mint as dating evidence on a building!) A bit more research online narrowed it down to the 1960s, when the porch was embellished by the Friends of the Guild Chapel (formed in 1954).
