for this particular set, each block represents a different family member. The iconography illustrates their uniqueness without being too literal, the names represent each family member and their kids. They stack in any order and spin freely via a female/male connection. The cost of this project is 250.00 per family member. Each member can choose whatever images define them, 4 images per member. It's best to contact me directly so we can make a game plan to gather all of this digital info and put it together. This project is very time consuming and not something that can be a rush order. But it's very cool!
