I had time to do some searching while my son was at practice. The Seals logo and lettering seems to match better with Seals Uniforms from 1938-1939, not the 1915-1920 dates mentioned by Egner. Or, the 1927 date mentioned by the E-bay seller. See the images below from Ebbets. The pennant logo is not an exact match of the logo used by Ebbets (see the hat), although it is similar in many ways. The Orange lettering on the 1939 jersey is pretty close.

And, trust me, I'm curious to know about the true age of the pennant, even if it is more recent. I know it doesn't match the E-bay one and does match the Egner book one. I also believe mine has a decent amount of age. How much age? I'm not certain.
