Metallica Kill ‘Em All Logo Enamel Pin

Very rare Metallica logo pin from the 1983 Metallica “Kill ‘Em All for One” tour.
The back reads “Ⓒ R RH INC”, which stands for ‘Rockn’ Roll Heaven’, the record shop of Jon and Marsha Zazula.

Also known as Jonny Z, Zazula was the owner of New Jersey’s iconic Rockn’ Roll Heaven store and founder of Megaforce Records. Zazula became an essential factor in launching the career of Metallica and released their first two albums.
