TLS by the members of great arena rock powerhouse, Def Leppard. The appreciation letter is addressed to "Don" Masters and dated September 1992. It is on the letterhead of their management company Q Prime. Excellent quality signatures ( Joe Elliott, Rick Savage, Phil Collen, and Rick Allen) are in black Sharpie and include a priceless one-armed drummer doodle by Rick Allen! Slight edge wear and toning do not diminish this EX quality TLS.
