Great American Ball Park's row ends feature the Reds' "wishbone c" logo throughout the park. GABP is one of only two parks in the majors to feature red seats.
The other red seat park is Busch Stadium. Busch's row ends are quite nice. They have the Cards' "bird on bat" logo cast into the seat post and the features of the logo painted on. It is clearly one of the best and well thought out in the entire league.
Miller Park has green seats and throughout the park on the row ends feature the above logo. It appears to be a giant batter hovering over the Miller Park dome. I don't know the significance of the logo, but it is also on the park's dedication plaque.
Minute Maid Park, formerly Enron Field, features the above row ends. Luckily for the Astros, they did not incorporate the Enron Field logo on to the row ends. This logo is actually also the logo for Houston's Union Station, the rail station that neighbors MMP. I don't know if this logo is a historic one or if it only dates back to the renovation of Union Station that was part of the ballpark's construction. In the planning stages of the ballpark, it was actually known as "The Ballpark at Union Station".
PNC Park is one of the better parks in MLB. It features a simple Pirates logo on its row ends. Since yellow or black would be odd seat color choices for a MLB park, they went with blue. (The neighboring Heinz Field football stadium actually does have yellow seats.)
As I mentioned above, Wrigley Field does not have row end figurals. Since all of its seats are plastic, the seat posts likely only date back to the 1970's which was a dead period of sorts for these ornaments. I have never seen any pre-plastic era seats for Wrigley that feature these.
