Steve Canyon promotional strip

Fun piece done like a comic strip but to advertise newspaper distribution and delivery boys/routes. Nice homage to Flagg's Uncle Sam recruitment image of Steve in the first panel. A nice Caniff girl in the second panel(I am embarrassed to say I have not read far enough into Canyon to encounter her yet). There is a paste up of smoke over the original Caniff signature and then a pasted on signature in the final panel. The guy in the background is also an add on. Holding it up to the light, it looks just like a suburban street and so the reader was added later. I am guessing this is from the early 60's. Steve never wore a helmet until he started flying jets in the mid 50's so this could potentially be a later 50's piece too. Regardless, fun stuff by my favorite strip artist.
