Over 30 years ago, was working on a presentation software that shipped with a bunch of (vector) clip art and remember using the (raster) graphics from the CIA World Factbook as a base to create vector (WMF) versions of the flags of various ‘new’ countries at the time (following the breakup of Yugoslavia) that were missing from the set that our art vendor provided to us.
The Croatia flag in particular took quite a while to trace/draw (by hand).
