The image is a vintage botanical illustration featuring two depictions of lichen on rocks. The background is a pale yellow, giving the impression of aged paper. **Top Illustration:** This shows a rectangular piece of rock covered in a colorful lichen. The lichen is predominantly green, with splashes of red, brown, and yellow. The pattern is intricate and organic, resembling a miniature landscape with winding paths and clusters of growth. The lichen appears to be a foliose type, with leaf-like lobes. **Bottom Illustration:** This depicts a similar piece of rock, but covered in a different type of lichen. This lichen is crustose, forming a dark green, almost black, crust over the rock surface. The texture is more uniform and less leafy than the lichen in the top illustration. The surface is covered in small, rounded bumps. Both illustrations are detailed and appear to be hand-drawn or hand-colored. There is a small number '223' in the upper right corner. At the bottom of the image, there is text that reads 'July 1897. Published by S. & W. Watson, Ltd.'
