Object-based advertising
This vendor cooks up blocks of rice candy in his home nearby, packs them into his carry-basket, and brings them down to this mini-park near a busy bus stop to patiently perform the work of breaking the larger blocks of candy into bite-size pieces and placing them into small plastic bags. The tool he uses to break apart the candy - picture a metal shoehorn that has been bent in the middle - also serves as "acoustic advertising": the sound of his hammer upon the metal implement notifies passersby of his presence.
Borrowed, stolen, or otherwise hijacked (depending upon who you ask, naturally), a traditional symbol becomes a modern advertising medium.
Out front of a combination photography shop and Chinese traditional medicine dispensary, fresh medical ingredients have been cut up and set out to dry in the afternoon sun, filling the entryway with herbal fragrances. As Chinese medicine focuses more upon prevention of illness (rather than the treatment of illness), the olfactory and visual presence of these drying ingredients in this high foot traffic area may serve as effective (if unintentional) advertising for the clinic; the thoughts of passersby may be drawn towards the last time they imbibed Chinese medicine, or may cause them to reflect upon their health (or the health of their loved ones).
