If you don't have the 2 patches in front of you, it's quite easy to differentiate the original from the reproduction.
Here are 3 obvious points :
The inside of the ear is over-embroidered on the reproduction
The inside of the eye is over-embroidered on the reproduction
The inside of the mouth is over-embroidered on the reproduction
On the original version, the 3 zones mentioned above are not over-embroidered.
Beware because this reproduction is not only sold on the internet.
Indeed, it can also be found on well known collectors meeting exchanges!
