...then write a kids book, with a moral story, just had mine purchased off me for royalties. That's a lump sum, payments for life plus commission for the first 12 months.
happy days.. and I can advertise myself as published now. although it means I cant post it here as that would be costing the publisher moneyz and I have a contract to keep to. It takes 3/6 months for finished prints but  if anyone is interested I'll post some info in the coming months.

NB: I suggest research be your first port of call, there are a lot of different types of 'children' according to publishers and each demographic requires different paradigms. but made more off one sale than years of selling paintings prints and ideas so do it. DO IT
