It was more likely to have been a back-projection of a conventional image. Holograms are images resulting from interference patterns and can only be viewed if one is looking at the pattern. They are formed from coherent light and have a characteristic "speckle" or iridescence. (Most people have no understanding of what a hologram is, or how to recognize one.)
