Overview

A mid-century promotional wall calendar featuring high-quality lithographic reproductions of John James Audubon’s 'Birds of America'. This specific set includes the iconic Ivory-billed Woodpecker and Steller's Jay, printed on heavy textured paper stock.

Story

In 1948, these calendars brought the high art of the 19th century into the average American home. The Ivory-billed Woodpecker featured here was already a ghost by then, having been largely considered extinct since the 1940s. It represents a moment when corporate America used natural beauty to sell the idea of 'security' and 'longevity'.

Maker / Origin

The Northwestern Mutual Life Insurance Company began this famous calendar series in the mid-20th century, becoming one of the most successful corporate branding campaigns in history. They chose Audubon's work because his name was synonymous with American heritage and meticulous detail, qualities the company wanted to associate with their insurance policies.

Condition & Value

The pages show visible edge wear, some creasing, and minor foxing (brown spotting) consistent with age. The Ivory-billed Woodpecker page has a significant diagonal crease which reduces its individual value by about 40%.

Market Analysis

Comparable demand stays strongest where maker, originality, and venue confidence line up. Broader examples still trade, but the range tightens quickly when provenance, condition, or selling lane fit is missing.

Value Drivers

  • Strong maker attribution with credible period details
  • Better-than-average condition for the category
  • Broader demand rises when presentation and finish feel intact

Concerns

  • Decorative-only demand limits the ceiling
  • Surface wear or missing provenance can compress the range fast
  • Regional sale lanes often underperform specialist venues
