Before a reel goes into production, a test reel is made to check for cropping, color, sharpness, etc. These reels are for internal use only or to get approval from the customer, and are not for re-sale or publication. They may be of interest to the collector when the production and the test reel have different images or when the test reel never went into final production. This, then makes the Test reel very scare.
Each image retains its full color and there is NO spidering, NO mold, NO violet spots. No bubbling on the reel.
