Howard Finster! Guided by voices and inspired by a wordy God, the untutored painter Howard Finster printed inspirational encomiums around all the charmingly blocky images he drew. He covered his environment - house, yard, homemade museum, etc - with paintings and detailed commentary.
In the process this late fanatic became America's folk art darling. See Finster's work and more at artspace, 710 Texas St, downtown Shreveport. The Folk Art exhibit, Feb thru March, is fascinating.
