This is a vintage, hand-colored architectural plan or survey of John W. Audubon's Homestead, titled 'The Blackwell Survey'. It's presented as a bird's-eye view, showing the layout of the property. The top portion of the image depicts the house itself, a large, multi-story building with a symmetrical facade. It's surrounded by mature trees, creating a lush, green setting. A long, curved driveway leads up to the house, and there's a hint of landscaping around the building. The lower portion of the image is a detailed plan of the garden and grounds. It features a formal garden layout with geometric beds, pathways, and a central focal point. The garden is divided into sections with different patterns and colors, suggesting a variety of plants and flowers. There's a large, curved lawn area surrounding the garden, and the entire property is enclosed by trees and landscaping. The overall style of the image is reminiscent of early 20th-century architectural drawings, with a focus on detail and precision. The colors are muted and pastel, giving the image a vintage and nostalgic feel. The text at the bottom indicates that this is a survey of the property, likely created for planning or documentation purposes.
