Where can i buy vans with space invaders on?

Quite a while ago i saw in a pair of mens black vans with multicolored space invaders on in a Freeman's??? catalouge (I think) . I saw them later in schuch as well but they were out of my size. I was wondering if any-one knows where i could find some?

um... why do you want these, but you could go on e bay and see if they have any on there!!good luck
