"Old Apple Tree; East of Castleton, ON, 1983" is a vibrant oil on board painting by Alan Collier, an artist whose life spanned from 1911 to 1990. This 12 x 16-inch artwork is signed by Collier on the bottom right and carries the date of its creation, October 2, 1983, connecting the viewer directly to the day of its inspiration.

The painting captures the majestic presence of an old apple tree, its gnarled branches stretching out against a backdrop of a fiery autumn sky. The leaves are depicted in a kaleidoscope of fall colors, with warm oranges, reds, and purples dancing amid the cool blues and greens of the distant landscape. Below, the ground is a carpet of fallen leaves, mirroring the fiery display above.

Collier's brushwork is both dynamic and precise, with bold strokes that define the solid, dark silhouette of the tree trunk and branches, contrasting with the more impressionistic touches that bring the leaves and sky to life. This interplay of techniques creates a sense of depth and movement, evoking the crisp air and fleeting nature of the autumn season.
