-( This trophy can be overlooked, so be careful. )-
Act I (Chase the Pigeon): Right after dropping down the trash chute, investigate the trash near it to find a bottle. As a part of the progression, you will need to use this bottle to solve the puzzle within the first scene. However, attempt to trade it with the Garbage Dealer instead to get this trophy. This is missable as the bottle will be completely used up should you proceed with the puzzle instead of deviating.
