I've just had a quick look at my catalog. Here's examples that I see with this graphic or close variations.

• Yankees
• Boston Braves
• Phillies
• Senators
• Brookly Dodgers
• Orioles (The Yellow Orioles Pennant is from 1947)
• Red Sox
• NY Giants
• Cubs

I think it's fair to say that they dates from the 40s - the early 50s. The Braves moved from Boston in 1952. The Dodgers and the Giants moved from NY in 1957.

Hmmm … Senators is WGN. Braves and Red Sox are Ad Flag. The Giants at the bottom of column 2 is a seperate unknown company. The others all seem to be the same company. This includes all the late 40s team pennants with names like this one

I was gonna say the same….similar motifs but definitely different makers.

What's nice about the this 1950 NL champs pennant is the amount of hand written script utilized on it. When I'm trying to ID a pennant, I look closely at the artwork because I know, more often than not, the same artist produced the art featured across the series; and artwork includes scripts utilized. In the 1940s, the artist couldn't just dial-in whatever font they desired like you can on a word processor today; they had to make the font. It's extremely personal to the artist.

For example, if you look at all the pennants from Trench's stadium pennant series in the 1950s, you'll see the same unique script utilized for the ballpark name, e.g., "Sportsman's Park"; "Milwaukee County Stadium," etc. That script is essentially Trench's signature.

Your 1950 NL champs pennant features an entirely different script. It's definitely not by Trench's artist. It does appear similar to WGN's, as WGN's ca. 1950s ASG pennants featured a similar cursive script. Greg, compare WGN's 1950 ASG pennant featuring Comiskey Park and the AL/NL "book" roster. Similar cursive scripts, right? But compare the names "Roberts" and "Hammer" ... although similar, they appear different to me. Different "R" and different "H" as best I can tell from pictures....

Maybe you can confirm by giving us a side-by-side comparison, since I don't own either pennant? :D

Anyway, my suggestion: follow this unique script to a known pennant by maker, and you'll have solved the greatest pennant mystery of the 20th century.

What rules out WGN is the way the spine is stitched. I don’t know how to describe it but it appears to be “double stitched” on the back, for reinforcement, which is why you rarely see loose threads on these. Keezer, Ad Flag and ASCO had similar stitching. Trench and WGN are different in that regard. I’ll have to take pics when I return home.

Yikes. Definitely not vintage.

Cool pic of Jackie right after his retirement. But completely wiped out by the fact that someone applied tape to that beauty of a pennant! Noooooooooooo!

Confirmed. Different artists. The upper case "J"s and "R"s do not match.

The mystery continues....

It seems as if the sliding runner pennant company is in the “top 3” as far as quantity made (guess, of course). Trench and WGN being the other two. Next tier is Keezer, Ad Flag, ASCO.

Anyone get that beautiful orange Orioles scroll pennant that just sold on eBay?
