Michael Diamond (Mike D), Adam Horovitz (Ad-Rock), and Adam Yauch (MCA)
The Beastie Boys - Grammy Award-Winning Hip Hop Pioneers · Music - Hip Hop / Alternative Rock
Grand Royal / Capitol Records / Def Jam

Era
Circa 1998-2004 (The Hello Nasty Release / Post-Release Era)
Item Type
CD Booklet / Front Insert
Condition
Very Good to Excellent. Minor shelf wear to the edges of the booklet; signatures are bold with no significant fading or smudging.
Rarity
Moderately rare. While they signed frequently during tours, a full-member set including the late Adam Yauch (MCA) is highly sought after and supply is fixed.
Overall Assessment
A high-quality, authentic-appearing full band signature set on a quintessential 90s album. Highly desirable for any serious music collector.
Authenticity Assessment
Highly likely authentic. The signatures exhibit the correct fluid motion, pen pressure variations, and spatial orientation typical of late 90s in-person Beastie Boys signings.
Signature Style
Casual, fast-paced 'street' style signatures. Mike D features his name in blocky, energetic letters; Ad-Rock includes his trademark 'A' and 'R' flourishes; MCA is a vertical, rhythmic scrawl with three distinct underlines.
Signature Characteristics
Mike D: High-pressure vertical strokes. Ad-Rock: Loopy 'A' with a sharp 'R' descend. MCA: Fast vertical zig-zag with three dashed underlines reflecting his 'MCA' initials in a minimalist form.
Ink & Medium
Black permanent marker (likely Sharpie brand) on a semi-glossy paper CD booklet/insert.
Item Description
Front cover insert for the 1998 Beastie Boys album 'Hello Nasty', featuring the iconic sardine tin artwork.
Estimated Value
$600.00 - $900.00 (higher if professionally certified)
Comparison to Known Examples
Consistent with 'Hello Nasty' era promo signings and 1998/1999 tour examples. The positioning of the three signatures is a common layout for this specific booklet.
Authentication Tips
Look for the speed of MCA's signature; it should look like a heart rate monitor spike with no hesitation. Ad-Rock's 'A' usually crosses through the left leg of the letter.
Certification Recommendation
JSA (James Spence Authentication) or PSA/DNA are the industry standards for multi-signed music memorabilia.
Red Flags
No significant red flags observed. The ink flow shows natural 'pooling' at start/stop points consistent with hand-signing.
Provenance Notes
Ask if the item was obtained at a 'Grand Royal' pop-up shop or a tour venue between 1998 and 2004 to bolster history.
Historical Context
Hello Nasty marked the band's return to a heavy hip hop and electronic sound, winning two Grammys in 1999. It is one of their most celebrated eras.
Market Trends
Beastie Boys items have appreciated significantly since MCA's passing in 2012, particularly items featuring all three members.
Investment Potential
Excellent. As a complete set of a legendary, defunct group, this is a 'Blue Chip' music collectible.
Similar Autographs
Run-DMC, Public Enemy, or Grandmaster Flash signed items are comparable for Golden Era hip hop collectors.
Display & Preservation
Frame with UV-protected glass and acid-free archival corners. Avoid direct sunlight as Sharpie ink can turn brown/purple over time.
Interesting Facts
The band was notoriously difficult to corner as a trio in later years, making triple-signed items significantly more valuable than solo signatures.
