Have you noticed the “hidden” symbols in some of the worlds most famous logos. Surely one of the most popular ones has to be the FedEx logo.
It may not be so obvious at first glance but if you look closely you will notice an arrow between letters “E” and “X”.
Spartan golf club is certainly a good example of a logo with “double meaning”. There is a golfer swinging his golf club and if you squint a bit you will see clearly a spartan head.
