hello.....I picked up these two medals as a group...the campaign medal appears to be of late 50's construction but I am wondering about the other medal....it appears to be older and more period, I have not seen many of these and have seen it described in two different ways....

just wondering what the official name is...and how was it awarded....military or civilian related ?

thanks in advance for your input.....

the pair

medal in question - front

back
