Great vintage lamp. No major damage chips, cracks, dents, or dings. Finish wear, scratches, and marks. Originally and still is marketed as a portable heat lamp. I thought it was just a cool lamp that could be used in many different applications. The base can be mounted on a screw or hook, or by the clip on bracket that is attached but removable. The lamp is completely adjustable. The angle can easily be changed and it can also swivel or rotate to completely change the direction of light.
