I am also very sorry to hear this. Despite living in Tennessee, Sherman used to drive all the way down to our TCA Southern Division meets in Florida 4 times each year for many years and set up several tables of postwar goodies with reasonable prices. He was one of the first members I met when I joined the club and he was so very helpful to this then young collector and was always smiling and friendly. I would always look for his tables at the beginning of each meet.
My condolences to his family.
