A lot of this stuff is bought for different reasons other than just as a collectors investment. Especially stuff bought regionally. In fact probably most of what is bought is for commercial or personal placement with out a thought towards future returns. So as redundant as most of this stuff is people can attach a certian value to these image just because they "know personally the image maker" It does not happen very often that individual image creaters come out of the gates with an obsolute personal concept and exacution consistantly placing themselves apart from the rest of the group. So as in all mediums there is a repetitious glut of ideas that are sold. Landscapes are certainly one of those.
