This is a black and white enlarged image of a thimble overflowing with chip transistors and a larger transistor (shown for comparison) next to it. There are small chip transistors scattered on the floor. Both thimble and large transistor are under a round spotlight which is coming from the left side of the image. The background is totally dark and black. The caption outside the image, in black, at the lower left of the image is "V20-9298". This is part of the original print and not on a label. Written on verso side in blue ink is "SLT Transistor" on the upper left side. Directly below it in pencil is written "#1272". At the right edge of the verso image is "L-1-3", 'IBM", and "3" written in pencil.
