Here is the answer if you are looking for the Wheres Wally Advent Calendar 2020 CAMERA on day 2.
The actual CAMERA you’re looking for is tiny compared to the image you see in the advent calendar door, what you see behind the door is not actual size. Makes it a bit harder, but that’s why you’re here!
Almost exactly right slap bang in the center of the advent calendar on door number 19 is where you’ll find the little camera. Or follow your gaze in a straight line to the right from the KEY you found yesterday and you’ll see it just to the right of the cake carrying the Santa.
