The great nephew of Edward Elgar has appealed to thieves to return important medals they stole from his birthplace museum in Worcestershire.
They were taken, along with a signed photograph on 27 June and Mark Grafton, who is also a trustee of Elgar Foundation, said: "He had given his life to music and so much of it was stolen when these two medals were taken."
West Mercia Police believe two men got into the museum in Lower Broadheath by forcing open the front door and then smashed a display cabinet to take the medals.
They have identified the type of trainers the pair used and are appealing for anyone offered the medals to come forward.
Mark Grafton also told the BBC's Crimewatch Roadshow, "the reaction of the family was anger, disappointment, frustration, sadness."
He added: "I don't think you can put a value on them, they are irreplaceable."
