Lenticular means it is it changes depending on how you look at it. The front side only is lenticular. From the front, you can see either Pokemon 151 or the Mew. The back side is not lenticular and is a nice smooth gloss. 

Please see my pictures to see the change in image as you look at it from the left or the right. 

Measures 17.25 inches wide by 24 inches tall. I also attached an image showing it is quite thick. This poster does not fold as it is quite thick. It is slightly bendable and returns back to its shape. IT WILL BE SHIPPED IN A BOX to keep it safe as folding it would probably crack the plastic. It has two holes on the top for hanging. I have attached an image to show one of the holes close up. PLease alno be aware that the lenticular side has some small smudging. It isn't dirt as it cant be wiped off. Maybe from shipping several poster together and thye rubbed against each other a bit. I tried to attach an image (the last one) to show the smudging but I can't really see it in the photo. In person from even a few feet away you can't see it. But if you look up super close and shine it in the light just the wrong way you'll see small smudging on the surface. I actually didn't see it on any of my posters until after I posted this ebay listing as they are so minimal but I am being sure to let you know as I am as transparent as possible that the small smudges are there but you will only notice them if you are really looking up close with the light shining on them at an angle.

Thank you for looking at my items and my shop. Have a great day!
