Shell - Conchology - Conch Notebook

This is a conch shell. In the old days, they used these as phones. They never worked well, always had a static sound, and inserting more coins never helped much. But they were portable. Later people found they worked better when they were in ear shot of the people they wanted to speak too. Looking for POSTERS of this or any of these designs? Would you like to learn how I create these?
