Talk:Superman (comic strip)

Hi! I've been reading the early Superman newspaper strips on their 70th anniversaries, and I've run across a snag. Everyone seems to agree that the Sunday strips began on November 5th, 1939. Yet I'm reading the daily strips from April of that year, and above each of this week's installments has been an announcement: "Superman in color - starting this Sunday in the Post-Dispatch!" So...did the color Sunday strips begin in April? I don't know whether to begin them today or not! Does anyone know the story behind this seeming discrepancy?
