I remember seeing the stall in Camden a while back.
It always makes me laugh when 'traders' at UK boot fairs (flea markets) have vintage Star Wars figures for sale at insane prices - most look like shite, massive paint loss etc. I always have a look though for Sandpeople with hollow tubes and other gems these plonkers don't know about. Someone quoted me £80 for a loose beat up C3PO, I just laughed!
