EXTREMELY COOL TRUE 3D HOLOGRAM of an anatomically correct model of a brain and musculature in the skull (2-channel image). This hologram was created in the laboratory of Polaroid Holographics in Cambridge MA in the 1980s (which closed in the mid 1990s). The image was created from two extremely realistic models (models created by a medical miniaturist, hologram made originally for inclusion in a medical encyclopedia). This is a two-channel hologram, one being the brain alone shown in the skull cavity, the second has musculature and eye etc.. This image is not for the faint of heart, it is medical scientific in nature - awesome gift for a doctor or anyone in medical or bio-sciences fields. This is an extremely 3D true film hologram and must be viewed under a quality illumination source to be seen in it's full glory, which can be direct sunlight (not in shadow or behind a cloud), halogen light, streetlamp at night, single LED etc. It will work in diffuse such as fluorescent or shadow light but not well. The hologram is 3.2" placed on the surface of a black bent-lucite deskstand approximately 5" high and 3.75" wide (with the area bent back to serve as a stand about 3.75" X 2"). The stand is angled backwards in order to best catch the light. The film color is red, though the hologram is a green/gold monochromatic image. This product is shipped in a zip-lock bag for protection. Note that the same image is also available matted ready to frame (as a different listing). If you have any interest in holograms, human anatomy, the brain etc., this is a must-have for a great price! Thanks for your interest. Holograman
