Vintage 1950s-1960s Lucky 4 Leaf Clover Keychain, Zachary's Esso Cashiers, NC For Sale

Keychain from Zachary's Esso Service, Cashiers, North Carolina with an actual 4 Leaf Clover encased inside a bubble capsule.
To date the keychain, researched Zachary's Esso Service and found that it operated in Cashiers from at least January 1951 until the Esso Brand was retired in 1972. The phone number listed on the keychain for the Esso Station is only 4 digits, which went out of use in NC in the late 1960s.
The Clover in the keychain is completely intact. It is a uniform greenish tan in color. The clear bubble is near pristine, completely transparent with little to no visible scratches. The lettering is in good shape and completely legible. One small spot on the word "Lucky" between the "U" and "C" has lost some of the gold coloring. The reverse side has minor scratches on the end with the chain. It is not known if the chain itself is original.
