Hartford Whalers

The Whalers' uniforms underwent a complete redesign from the ones they wore at the tail end (no pun intended) of their WHA years. Then, the team's colors were green and gold. The gold was replaced by royal blue. The WHA crest featured the letter "W" with a spear running through it. The spear disappeared, and a new crest was introduced, featuring a "W" with a tail emerging from the top. In one of the most ingenious designs ever, the negative space in the logo forms the letter "H."
