A thought about magical treasures

Why is it that the only magic items you ever see around are things that are useful for adventuring? There never seems to be, for instance, any magically-animated paintings (ala Harry Potter), enchanted farm or craft tools, potions of fertility, or things like that. Maybe I should make a chart about it. In the meantime here's all the ideas I could think of int 20 minutes and I'd love to hear your suggestions if you're reading this.
