Czechoslovakian Stamp Designs

I'm a long-time fan of Czechoslovakian postage stamp design and have posted some of my own favorites stamps in the past here. Oliver Thomas has a wonderful Flickr set of additional Czech stamp designs including those here and they are very well documented. The variety and styles of the hand lettered text on these stamps is stunning.
