Can anyone identify this set?
Welcome! This collection of pieces might contain some LEGO pieces, but is mostly another brand. The bottoms of the bricks and plates have patterns that are not typical for LEGO, and LEGO does not make a large wedge plate like the light-grey one on the right. Furthermore, LEGO did never make a large tree stump and tree with face as shown in the middle of the picture. As such, even though the seller claims this is "LEGO", it is not.
