Thank you Tiem! At right is a 1958 airmail stamp of the Temple of Artemis in Jerash. This is the lowest value (make up after a rate change?) of six, each printed in different colours. 
Here is Hadrian's Triumphal arch in Jerash, many different colours and values were issued from 1996-1998(?). Currently, the arch looks different due to reconstruction efforts. Check out this website for detailed Jordan stamp information. 
Thank you Randal! Jerash stamps from a 6v tourism booklet of The Hashemite Kingdom of Jordan.
