This is an original Aladdin 201 (Ribbon) shade. It has been reproduced, but the reproduction shades are lacking in detail compared to the originals. The easiest way however to tell the reproduction from the original is to look to the "valley"! If you see the mold line running down the shade into the shallowest area of the glass (the valley), then the shade is an original. If the mold line runs out to the widest part of the glass (the peak) then it is a reproduction. Just remember that originals are always found in the "valley!"
