Finding an art item should not be hard, as there are many art galleries that sell expose and sell different things. You will find beautiful paintings or photos, sculptures and even furniture pieces that are considered art. As beauty is in the eye of the beholder, everyone is entitled to their own opinion.
However, art critics are very exigent when evaluating something, and based on their expertise, you will find different opinions from different critics. As everything is filtered through their own eyes and experience, the different items of art will be differently evaluated.
