Not sure if this is Skagway, but it sort of looks like it. The sign says Mascot, perhaps the Mascot Bar on Broadway, but quite different.
Daniel Murphey was in a bar fight on May 10, 1908 with William Hoskins also in 1902 with Jimmy Burke, a longshoreman, at the Mascot Saloon. Skagway was still a wild place after the gold rush. (Oh those crazy Irishmen)
