Let me call my expert in mid-century collegiate pennants and have him come take a look.

The Yellow Jacket logo on that pennant was designed in the Late 50's/ very early 60s.

I would guess that might be from when we were transitioning from Golden Tornadoes/Engineers to Yellow Jackets as official mascot. 40s-50s? From condition it does look like 60s.
