I have a PB WIP that features 7 named characters, each with some dialogue, and I'm hoping to find published picture books that also feature a big cast. I would exclude those with litters/clutches such as Make Way for Ducklings, because the ducklings are really one conglomerate character. I'm writing a science fiction caper and having the large cast feels like a better team than just 2 or 3 characters, but I'd like to see how introducing them all without overloading the reader has been done.
