OFFSHORE EUROPE N.V.

The green flag has a large white circle containing a large black C around a smaller black E. The E’s upper arm meets the C’s upper end, and its lower arm merges into the C’s lower curve. Rosanoski notes that E might be read as F and C as part of O, or the letters might relate to a native-language name. The black funnel carries a broad band of the flag design, edged white below.
