Susan is right (she's always right:)), that's simply not how we think of art in the English-speaking world. The primary dichotomy is between fine art (what Frank called "art for art's sake" although this is not what they actually call it) and decorative art. These are very loose and conflicting labels, to be sure, but that's all there is. Here's an article that discusses the difference btw the two and the problems inherent in using these labels: http://reddotblog.com/ask-a-gallery-owner-fine-art-vs-decora...

There is yet another dichotomy, figurative vs. non-figurative, but that's not at issue here. In any case, it matters none to an English speaker whether a painting was created on an easel or someone's kitchen table. This "easel painting" just doesn't mean anything to anyone who is not professionally dealing with Russian art-related literature and such.

I said it before and will keep on saying it until the day I retire to greener pastures: things are often perceived and worded differently in different languages. Russian is HUUUUUGE on giving everything its "proper" label and putting it into its assigned little box, hence the outright disgusting proliferation of all kinds of pseudo-scientific classifications and terminology where other languages happily do without. English, on the other hand, favors verbs - i.e. labels for actions rather than things. Different national psychologies, perhaps?
