Late 1950s on the Dodgers. A great Dodgers Variation, but in that condition, it's worth very little. I would say $10 - $15 at best... it's just too faded and rough to be worth much more
In NRMT Condition, that one would be $125 - $150. I have also seen that same pennant with a "1959 NL Champs" overlay.
On Notre Dame, it's a tougher call. That embroidered, generic style spanned a few decades. Based on style and that type of thin cloth tassels, I would estimate 1940s, but there's a big potential variance on this one.
It could actually range from the 1920s - 50s. Sorry I cannot be of more help on that one. Neat pennant!
