Condition

Good to Very Good condition for a mid-19th-century legal document, showing normal folds, slight paper toning, minor edge wear, and stable iron gall ink preservation.

Rarity

Scarce and highly desirable, as legal documents wholly associated with the Lincoln and Herndon law practice are museum-grade historical artifacts.

Overall Assessment

A magnificent, historically significant mid-19th-century legal document carrying the partnership endorsement of Lincoln and Herndon, representing a prime artifact from Lincoln's pre-presidential legal career.

Authenticity Assessment

Likely authentic based on period iron gall ink, manuscript structure, and consistent signature characteristics matching known 1850s legal documents from the Lincoln and Herndon firm.

Signature Style

Formal legal signature reading 'Lincoln and Herndon p.p.' in the hand of William Herndon or Abraham Lincoln's endorsement 'A. Lincoln', exhibiting classic 19th-century legal cursive and distinct angular letter forms.

Signature Characteristics

Strong baseline, sharp angular strokes, consistent pen pressure appropriate for a steel nib dip pen, and characteristic 1850s legal signature morphology.

Ink & Medium

Period-correct iron gall ink on laid legal manuscript paper, showing characteristic brown oxidation over time.

Item Description

A two-page handwritten legal petition for mandamus filed in the Supreme Court of Illinois, June Term 1857 (The People ex rel. The Auditor of Illinois), featuring legal arguments regarding state debt and signed by the law firm of Lincoln and Herndon.

Estimated Value

$25,000 to $50,000+ depending on complete archival provenance and verification of Lincoln's exact handwriting contribution within the text.

Comparison to Known Examples

Matches standard exemplars of the Lincoln & Herndon law partnership filings from the Illinois Supreme Court during the late 1850s.

Authentication Tips

Certification Recommendation

PSA/DNA or JSA specializing in historical manuscripts, alongside authentication by recognized Lincoln scholars and manuscript dealers.

Red Flags

No significant red flags observed; the manuscript exhibits expected aging, iron gall ink behavior, and structural consistency for 1857 legal papers.

Provenance Notes

Essential to trace back through reputable auction houses, institutional deaccessions, or documented estate collections with historical paper trail documentation.
