TCMA is no stranger to retrospective baseball sets, especially for their earliest work in the 1970s. Many past players and teams reappeared temporarily on TCMA cards, typically as simple black-and-white designs with a common theme.
For today's set, I assume TCMA acquired a handful of Larry French photos, found him a willing interviewee, and decided to write a story that tied together his life and career. (The yellow backgrounds are from an eBay listing linked below; all six are postcard-sized and come in black-and-white.)
Larry French was a classic innings-eating pitcher in the 1930s, one of those guys who made 30 starts every year and won often enough to keep the owner happy. He pitched often enough and long enough, in fact, that he's one of only 90 pitchers to allow 3000 hits from the mound. It's a much rarer feat for batters to achieve, but also says something about your longevity and effectiveness as a hurler to hit the same mark. (HOF Phil Niekro holds the top spot and is the only pitcher to give up over 5000 hits.)
French's back text story--titled "The Porkchop Pitcher" on card #1--covers his baseball and personal life and reads much like TCMA's companion set about ballplayers stationed in Guam. Their brief biography, partially told in his voice, was co-written by Harrington "Kit" Crissey, who later published a WWII baseball book called Teenagers, Graybeards, and 4-Fs.
Value: An eBay listing asks $20 for five of the six cards, which isn't beyond the pale. They're hard cards to track down and I rarely see them online.
Fakes / reprints: I doubt anyone would make money faking obscure TCMA sets, even if it'd be easy to do with modern equipment.
