A man from London has been showing off his collection of milk bottles from dairies all over the capital.
Former milkman Paul Luke has been collecting them since he was nine years old and has more than 10,000 so far.
Each bottle contains the name of the dairy. and as most of them have closed down, Paul's collection is helping to keep their memories fresh!
The bottles are now filled with polystyrene beads. One of them is even from the Queen's dairy in in Windsor!
