Police are issuing two photos taken at a wedding in an attempt to reunite the owner of a bag that was recovered in Earlsfield just before Christmas.
The items, in a blue Ikea shopping bag, were found by a dog-walker on a public footway alongside the River Wandle, in the Haslemere Industrial Estate, on the morning of December 23.
Among the items in the bag was a digital photo frame containing a memory card.
Some of the photos show people at a wedding and officers hope the public may recognise one or all of the guests.
Detective Constable Riaz Karolia of Wimbledon Police said: "So far we have had no success in locating the owner of this bag.
"I am hoping that by issuing these images, someone may recognise the people involved and we can start the process of reuniting the owner with their belongings.
"The memory card contains images of someone's special day - if you know who these people are, please get in touch."
If you recognise anyone in the photos and believe you can reunite the items with their owner contact Wimbledon Police on 0208 649 3154 or 0208 649 4044.
