Dining at Large's Richard Gorelick took this photo of Orioles fan Abby Thompson posing with Mr. Boh at Oriole Park Monday.
The beer is served at several locations at the ballpark and at the suites on the club level as a special "Bucket of Boh's."
There is also a branded Natty Boh Bar on the first base side of the lower concourse, where the picture was taken.
Fans of craft beer should note brewers Heavy Seas, Evolution Craft Brewing, Flying Dog Brewery, Fordham Brewing Company, and Old Dominion have product on sale as well.
Brad Klipner has a partial beer menu over at his blog.
If you're just a fan of Mr. Boh, the character is scheduled to make some 40 appearances at Oriole Park this year, Gorelick writes.
One can only hope Kegasus doesn't overshadow him.
