This photo was taken at the Los Angeles Memorial Coliseum on December 8, 1957, as the Packers were completing their customary late-season West Coast swing.
My first thought—well... third, after "Look at all the empty seats!" and "Those photographers are standing waaaay to close to the sideline."—is that those Packers don't look like the Packers at all.
There's no gold to be found anywhere on those uniforms. White head to toe, with blue stripes and numbers.
This road uniform was introduced by head coach Lisle Blackbourn as part of a general uniform overhaul.
If the team didn't look like the Packers, they didn't play much like the Packers we're used to watching, either, falling to the Rams that day 42-17.
