Anyone collecting stamps pre-internet will remember the taunting task of looking up stamps from those dim b/w imagesc of printed catalogues. It could take hours to put a few stamps into collection. That's all changed now, thanks to online sevices any stamp can be identified in seconds.
Let's put this to test. The following are excerpts from a few selected stamps from around the globe. To even things up, I've omitted some vital information like the country's name. I've even included one old-time murky image (bottom) into the set. The pieces represent various small fractions of the original image. The smallest piece is only a few square mm –a private joke by the engraver and not really meant to be recognized,
Your job is to find useful (dis-)information related to printing, engraving, perforation, art, people or indigenous flora and fauna etc. to uniquely identifiy the stamp. You may assume that none of the stamps has any overprinting not showing in the smaller image.
To obtain the coordinates from the stamps progress one decimal at a time and remember to carry. For example, a set of numbers (a,b,...,f) gives you a coordinate like this
(a,b,c,d,e,f) → ab.cdef°
