Further to Geoff's reply,
Michel Catalogue # 191 through #195 Yemen (Kingdom) 10th November 1965.
Values 1/8th bogash to 6 bogash.
The 4 bogash (not shown here) [Space Capsule, and Alexey Leonov Russian Cosmonaut ] displeased the government, and post offices were obliged to blacken it with handstamps.
Typo :"astranauts" corrected.
