Yeah, I agree, their use of "hand" doesn't agree with our use of the word "hand." Then again, our use of "hand" doesn't agree with painter's use of "hand" either.
My point, really, is why should we feel threatened by this? Large portion of consumers don't care. Collectors who do care know the difference. We know what we mean. They know what they mean. So what's the problem?
By the way, I always get a chuckle when eating "home made" soup at restaurants.
