[bbpostcards]

I'm editing this post because I figured out the year. It shows the 1915-1916 Portland Rosebuds hockey team of the Pacific Coast Hockey Association (PCHA). This team was the first U.S. squad to play for the Stanley Cup (they lost to the Montreal Canadians). Hockey Hall of Famer Moose Johnson is in the top row, fourth from the left of the large images (see the posts below).

The postcard can be confirmed to the 1915-1916 season for two reasons. One, the first large player photo in the second row is Charlie Tobin. He played for the Rosebuds only in 1915, 1916, and 1917. Two, the advertisement on the Hippodrome where the Portland Rosebuds played (center of postcard) is for "Professional Ice Hockey, Portland. vs. Victoria, BC." While Tobin was on the Rosebuds, the Victoria team only played in the PCHA during the 1915-1916 season.

Team members that year were Tobin, Johnson, Tommy Murray, Delmar Irvine, Edward Oatman, Tommy Dunderdale, Wilfred "Smokey" Harris, Charles Uksila, and Alf Barbour. Any more ID help would be welcome.
