I contacted the editor of the newspaper and asked if he would be willing to let me have a copy of the letter Manson wrote and he agreed! I expect that Manson has caused a few editors to have a WTF moment when it came to editing his letters.
And here is the envelope the letter came in, I was sent B&W copies.
A couple of weeks later Kenny Calihan, Manson's prison buddy, also wrote a letter to the AVA. Enclosed with his letter was a prison form of Manson's that Manson signed, I guess to show the newspaper that he really was a buddy of Manson. I'm not at all familiar with what this form is all about but it seems to be called an ANNUAL/PRE-MERD REVIEW. If anyone knows what this form is for, please, do tell!
