Dave Stewart

Era

Modern Era - Post-retirement (circa 2010s-2020s)

Item Type

8x10 Glossy Photograph

Condition

Near Mint. The autograph is bold with no smearing or skipping. The photo paper appears crisp with sharp corners and no visible surface scratches, creasing, or UV damage.

Rarity

Common. Dave Stewart is a generous signer through the mail and at paid appearances, making his autograph readily available to collectors.

Overall Assessment

A high-quality, authentic example of a core 1980s star. The two-tone ink (blue and red) and biblical inscription make it a more desirable specimen than a standard signature.

Authenticity Assessment

Highly likely authentic (95% confidence). The signature displays the characteristic fluid, vertically-oriented loops and unique stroke intersections consistent with Stewart's later-life signing style, particularly on larger media.

Signature Style

Stylized script with heavy vertical emphasis. The signature features a distinctive looping 'D' and 'S' that blend into a fast, rhythmic scrawl. It includes the biblical inscription 'Josh 1:9' (Joshua 1:9) in red ink.

Signature Characteristics

The signature shows high 'pen speed' with no hesitation marks (tremors). The 'D' starts with a sharp downward stroke, and the 'S' is often a mirror-like loop of the first initial. The baseline is consistent, and the ink flow identifies it as a hand-signed piece rather than an autopen.

Ink & Medium

Blue permanent marker (likely Sharpie) for the name; Red permanent marker for the inscription. The blue ink shows strong saturation with no significant fading; the red ink is vibrant and sits well on the photo glaze.

Item Description

An 8x10 color glossy photograph featuring Dave Stewart in his Oakland Athletics road grey uniform (number 21) in mid-pitch delivery. This is a classic action shot from his peak years in the late 1980s.

Estimated Value

$30.00 - $55.00 USD. Value is bolstered by the religious inscription but limited by the volume of material Stewart has signed throughout his career.

Comparison to Known Examples

Matches perfectly with Stewart's known 21st-century signing habits. Earlier career signatures were often more compact; this elongated version is typical of his modern private signing sessions.

Authentication Tips

Look for the specific 'loopy' nature of the letters that lean slightly to the right. Stewart's signature often looks like a series of vertical coils. Forgeries usually fail to capture the speed and natural pressure variations in the rhythmic loops.

Certification Recommendation

JSA (James Spence Authentication) or Beckett (BAS). For items in this price range, JSA's 'Witness Protection' or basic certification is standard and costs roughly $20.

Red Flags

No significant red flags observed. The ink sits on top of the 'gloss' correctly, and the flow is natural and rapid.

Provenance Notes

Look for a sticker on the back from a known signing show or a JSA/PSA basic cert card. Many of these were signed during specific '80s A's' reunion shows or via his charitable foundations.

Historical Context

Dave Stewart was the ace of the Oakland A's during their late 80s dominance, winning 20 games in four consecutive seasons (1987–1990). This era represents the peak of 'Moneyball' roots and Oakland's last great dynasty.

Market Trends

Stable. Stewart remains a beloved figure in Oakland sports history. While not a Hall of Fame lock, his status as a big-game pitcher keeps demand steady among A's fans and World Series historians.

Investment Potential

Low as a financial asset. This is a 'collector's piece' meant for personal enjoyment rather than equity growth.

Similar Autographs

Collectors may also look for Dennis Eckersley, Mark McGwire, or Jose Canseco to complete an '89 'Bash Brothers' era A's set.

Display & Preservation

Store in an 8x10 acid-free top-loader or frame with UV-protective glass. Keep away from direct sunlight to prevent the blue and red markers from fading over time.

Interesting Facts

Stewart frequently includes 'Josh 1:9' on his autographs ('Have I not commanded you? Be strong and courageous...'). He is famously known for 'The Stare,' a focused, intimidating glare he would fix on batters from the mound.
