As the BBC reaches the grand old age of 90, we have delved into the Echo archives to find these images which are all connected to one of the Beeb’s most famous programmes.
Stars of the show Helen Skelton, Konnie Huq and Matt Baker have all paid us a visit.
Others among you have visited the Blue Peter studios or raised money for a Blue Peter appeal.
See how many of these Blue Peter themed photos you remember.
