A Hedgehog in a cover reading a book at サンキューカード

A detailed illustration depicts a great hedgehog, probably a mother, sitting on a chair and reading a book to a smaller hedgehog, presumably her child. The mother wears a white dress with a white collar, while the child is dressed in a brown shirt with a white collar. The book is open and has a dark red cover. The stage is lit by a lamp with a white lampshade, shining a warm glow on the hedgehogs.
