Hello,  a few days ago I wrote about the  1949 UPU issue and showed a Ceylon stamp.  Here is the  more traditional Omnibus design I mentioned.  

Certainly a set I enjoy seeing and one to pay attention to because while most have a very low catalog value and can be found for a few cents in good used  or mint condition some do attract a small premium - this Falkland Islands set for example.

This again from my friends  British Commonwealth Album  here   -    and you might enjoy visiting his online store the Used Stamp Collector here.

Enjoy your philately    Michael   cddstamps.com
