off his trolley

there is man-of-the-street who ‘lives’ somewhere between paddington and oxford circus who collects the kind of junk i take photos of and put them in a trolley. i often see him in the morning transporting his trolleys through the streets of london.
today i saw him with 6 seperate trolleys, all piled high with junk.
here they all are:
trolleys 1 and 2 in front and number 3 behind (with the guy himself sitting down):
number 4 in front and number 5 off in the distance by the lamp-post
number 6 all nicely piled up
