Spot the Impossible with Common Sense!

These old scenes look normal — but one thing is from the wrong century. Sunglasses in a Dinosaur-Era forest. A drone above a medieval castle courtyard. A wireless keyboard in a 1920s café. Each vintage, sepia-toned illustration hides a single modern object that hadn't been invented yet in that era. The modern item is drawn in the same sepia tone as the rest, so you can't spot it by color alone — you have to recognize its shape. This is a simple observation quiz where you tap the modern item that shouldn't exist in that era.
