The first version I got from Milan Vodička, the second cube I got as a gift from Clément Gallet, who stickered around 80 cubes with the same pattern based on my pictures from Milan's design for the French Open 2008.
After solving Clément's cube, I compared the found solution with Milan's cube. Without calculating the possible solutions further, it is clear, that there are at least two solutions.
If anyone wants to calculate the amount of possible solutions, please let me know.
