I was basing my ID on this:
And this:
But photos of Ribes show similar scales. The leaf veins do look like Ribes but the shape could be either.
Its a drawing, not a photograph so there is always some artistic license. It could be either one.
So eselwyn, if you want leaves like that in a really big plant, choose a Ginkgo (but Ginkgo do make great bonsai). If you don't have space for a tree, choose a Wax Current. I'm not sure we can come to a conclusion one way or the other.
