[NTG-context] address labels

Hi contexers, I am trying to make context do what I want. What I needed this weekend, are address labels, which I want to fill with my own logo (not the addresse's). Making one label is no problem, but I rather would like to have context make and typeset a large number of them on a sheet, to be precise: 9x3 (sizes: 7mm x 32mm). Does anyone have a clue how this can be done? Kind regards, Robert Ermers
