Jimmy Olsen Adventures by Jack Kirby

Sure there's a bazillion rejected Kirbys, but these two are especially puzzling.  Only answer I can come up with is that Superman's Pal Jimmy Olsen was a tax write-off for DC, so the big kahunas had to make sure Jack dinnae get something too amaz'n published with the title, or sales would get too high (shades of Mel Brooks' The Producers).  bummer
