I took advantage of our kids' high school's lack of graphic standards (tightened up recently, with Boston College apparently asking the school to stop using a modification of its eagle logo; though the football team still uses the Philadelphia Eagles' helmet insignia) to come up with a water polo design one season. It just had to be eagle-ish and use the words El Camino or the initials EC.
Inspired by the motivational coaches on our daughter's team, and the cohesive boys' and girls' water polo program (and, I admit, a short-lived trend in baroque flourishes in TV and clothing design for the teen demographic), I created this fire-and-water look evoking a bird in flight. Water for the battleground, and fire for the passion with which the teams often played.
Here are some variations for a summer program, not yet used (left):
Maura's youth swim team changed its name from the Sea Wolves to the Piranhas. though I did artwork for the former, it's locked away in 20th Century digital storage and I've yet to get a chance to pry it out.
This is the mark (below) I did for the Piranhas, which I understand the team still uses.
