Star Trek TNG Hidden Image Stereogram framed poster in Palenville, New York

Star Trek The Next Generation Hidden Image Stereogram. This is a poster that hides a 3-D image. If you stare at it properly you will see the image, then you almost can't help seeing it. It's pretty cool. The hidden images are a large planet at the lower right side, a small moon upper right side, and 2 cloaked Romulan Warbirds center and left. The poster has a black frame. It measures ~28" W x ~22" H. Excellent condition. Questions welcome.
