From 50 Old Walls Volume 1 - a collection of 50, high-res jpegs, tiling horizontally and vertically. Perfect for game development, these 1024x1024 images are of weathered, tattered, delapidated walls, most of which are over 100 years old. The original pictures were taken in a historic New Orleans cemetery, noted for its above ground tombs.
The original image was 1760x1180 and the best area was cropped in 1024x1024. Photoshop Perspective was used to remove any bowing lines caused by the camera lens.
