This is a collection of exceptionally good line art of typical fantasy scenes, drawn in a style reminiscent of the illustrations in early D&D product.
There is lots of detail in each image - which come as a zip file of .TIF images as well as an 'overview' PDF.
The licence terms are generous and should fit the needs of most publishers and developers well.
This is really 'product' illustration, if you are looking for stock art for personal files, this may not be what you are after. But if you have an adventure or similar for which any of these scenes would be suitable, especially if you like the 'old school' feel, this is well worth consideration.
