Standing on a bridge overlooking the Rio Fuseri,
I took this photo of a water taxi and a gondola passing by something unique to Venice. This small step or porch was an official entry point for the building on the left; probably it was used both by visitors and deliveries - both coming by boat. On that afternoon it was being used to advertise the negozio, which appeared to be a dress shop.
I don't know whether they were expecting customers to arrive by boat that day. My guess is that they were advertising to people as they crossed the bridge.
