As far as the SCD Standard Catalog of Baseball Cards and Lefty's Diamond Stars card:
The SCD recognizes Lefty's "1934 green back" and "1935 green back". There is no mention of copyright date in the SCD.
As far as Lefty Grove:
I believe that they also pulled Lefty's tonsils in 1934 in the hopes of eliminating his arm problems. In 1938 (I believe) Lefty had his second fight with arm problems. At that point, they restricted him to pitching only once/week (on Sundays) throughout the remainder of his career (which ended with the 1941 season). While most of this is off the top of my head, I must cite Jim Kaplan's Lefty Grove biography as the original source of this information.
