Good thoughts here Professor K. I will defer to @Ameri here as he has done a lot more research in this area of Kane/Moldoff. From my in depth discussions with @Ameri, Moldoff would often come into the DC offices to drop off his work while Kane would sign his name on all of them. Kane was a cartoonist and perhaps did the Batman work in Tec 27-28 (teddy bear looking), but in 29 onward the Batman takes on a more sharper, sinister appearance. Moldoff was all over the map though and was the chief Hawkman artist for Max Gaines with All-American comics...Moldoff certainly did most of the 1950s Tecs covers and Batman stories and all of those have the bOb Kane boxed signature. To me, the Kane sig was meant to show ownership and not his art work, which Shelley gladly did to support his family.
