 Most of these featured adult "G-Men" even when marketed to children.The difference with the Junior G-Men was that it was designed to give boys a sense of participating in the exciting adult world of crime-fighting.That said, aside from the original radio program, a book, "Junior 'G' Men's Own Mystery Stories" (by Gilbert A. Lathrop, Edward O'Connor, and Norton Hughs Jonathan) was published in 1936 and a big little book by Morrell Massey and Henry E. Vallely the following year.
