Baddaren blå

If anyone knows the designer and when it was created please let me know.

To earn this classic little learn-to-swim badge you need to manage these three tests:
1: "the dip test". You have to submerge your head five times.
2: "the bubble test". Breathe in, hold your breath, submerge and exhale under water. Repeat five times.
3: "the gliding test". Glide for 5 seconds face-down with outstretched arms.
