i'm just a little curious as to what you imagine ocean as a product? just a book? or a pack of cards as well? (you can actually get POD cards these days)
I'm thinking small, slim book (maybe 8x5, 40 pages) illustrated with color comics. The cards don't HAVE to be cards. they could just be a list in the book. But I like them as card. Most probably I'll offer cards separately or as a package deal.
I've seen a few POD card places, but I don't know who to trust. Can you make a recommendation?
