I've seen it on many a Brooklyn Dodger pennant; but, never on a post-1958 Los Angeles Dodgers pennant. It was always monochrome when used on Brooklyn pennants. It was also used on some Yankees and Phillies pennants from what I assume to be the same era. Of note: the Phillies pennant was polychrome.

Interestingly, there's no New York Giants pennant featuring this moon-lit batter artwork; only San Francisco.

As to the others, the problem, for me, is that those latter SF Giants pennants in your evolution don't really look anything like what Trench was making for other teams in the 1960s--especially as concerns stadium pennants. The coloring, in particular, looks like it was applied with water colors, or a very translucent ink. It's also quite vibrant. Most likely these are by Trench, too; but ... I guess you couldn't exclude a copy cat by some bay area pennant maker that only made Giants pennants, right?

I just can't think of other Trench-made baseball pennants from the 1960s that resemble these....

I have always thought that those funky off-colored Giants Pennants were made by a local Northern Cal or Independent manufacturer. As you stated... no other teams had designs or colors even slightly resembling those early '60s Candlestick pennants. They are completely unique to the Giants.
