I used a lamellophone, pressed it on the glass of the aquarium and played. The fish responded, but their response was equivocal.

visiting cards I quickly designed and printed a card. The weather was bad the next day. Even so, two people were sitting outside. I gave the assistant the business card I just designed and a catalog, and I promised that I would send a more detailed description of my intentions.
