Hi all,
I've found these variations in the marks of two Omo Mini Smurf.
The Hiker:
[1] The first one, on the left, have the "Omo" mark on the head, and the "Peyo 1983" mark on the left arm.
[2] The second one, on the right, on the contrary have on the head the "Peyo 1983" mark, and the "Omo" mark on the left arm.
