The graffiti contest was one of the events that make up the festival that was held to showcase the charm of the old Bandung. Other events include music performances, carnivals, food bazaar, and exhibitions by different 'Old Time Communities' (Komunitas Djadoel) -- communities of collectors of vintage and not-so-vintage items from cars to radios and cameras to memorabilia from the old days.
Here are some of the things I saw at the exhibition:
Old typewriter, old movie camera, some old brass musical instruments, a gramophone, an original copy (I don't know what it means) of Stradivarius violin, etc.
