SCULPTURES made of shopping trolleys retrieved from rivers will be unveiled in Huntingdon tomorrow (Thursday). Artist Ptolemy Elrington has been commissioned by Anglian Water and has so far created a vole, frog and a dragonfly with a 6ft wingspan. These are the first of 10 sculptures which will tour the East of England on a roadshow travelling to Peterborough, Cambridge, Lincoln, Norwich, Colchester and Ipswich. The structures will be used to head an educational campaign to invite people to adopt a stretch of local river. Peter Simpson, chief operating officer of Anglian Water Services, said: "These sculptures are incredible works of art and an excellent way of highlighting the work we're doing and of getting more people involved." INFORMATION: The sculptures will be on show in Huntingdon for one day at 12.30pm in Riverside Park. In August, they will be exhibited at the Rutland Birdwatching Fair in Rutland Water.
