Honestly, most of them are still better than I could draw.
My thoughts exactly! What makes a bad art piece anyway? While they might not have yet mastered the brush or the canvas, these artists are obviously passionate all the same, and isn't that what matters? Real bad art is soulless and as such would offer no value, be it entertainment or contemplative, when placed in a gallery. That is a true Mueseum Of Bad Art, and I suppose the curators know this. I thought some of these pieces were quite incredible, actually.
I think it is quite simple to characterize MOBAs curation process. First, it has to be bad, in an ambition-vastly-exceeds-talent kind of way. Second (per MOBA rules) there is a price limit on each acquisition. It used to be $5, but may have been adjusted for inflation.
