I know for a fact that I prefer the murals to the bland, peeling canvases that the buildings once were.
I tried to find pictures of old Old South End, but was unable to do so. The below pictures are of a few the murals which I took pictures of while riding around. It was the only way to get the full images of some of them with my phone.
The painting is still going on now. More pictures and info can be found about the project here http://www.toledoblade.com/Art/2012/09/02/Dazzling-murals-light-up-Old-South-End.html
