DEF LEPPARD leopard-man vintage printed patch (1980?).
It comes from a late 1970s/early 1980s (stunning) collection, and is in a very good condition for its age as per picture. Note that it's slightly factory-asymmetrical.
This design was also used on a backpatch: https://tshirtslayer.com/patch/tres-rare-back-patch-de-def-leppard
