This is a set of large format animal posters on card stock about the thickness of a standard post card. They are neither overly flimsy nor very firm. The weight of the stock is such that they can't be rolled for storage (too firm), but also can't be bent without damaging them. I found them easy to hold to show to kids and easy to mount using just blue tack or masking tape. The quality of the pictures is mostly excellent, especially for large format pictures. Most are quite crisp and clear without distortions, blurring, or “noise”. The snake picture, spider, frog, gerbil, and tortoise are especially sharp and natural looking. Some of the other images are a bit grainy (the horse is the “worst” in showing grain) and a few others seem to be from lower resolution source images that seem to have been manipulated to look a bit better and show modest distortions. The fish image, for example, shows an edge that betrays aliasing and was over-sharpened. I think some of them also had noise added to them to disguise pixelation or other defects, but it's not especially obvious. All in all though, for the size of the images, these are very, very nice and only someone who wasn't scrutinizing them as carefully as I did would even notice these defects. I mention them here not because they are strong demerits, but just for to inform. They certainly are of sufficient quality to fulfill their intended purpose and are big enough to use on the walls of a room for teaching purposes.
