I used a nail scissor to get the parts together.
When I was finished (needs nearly 3 years work - of course not every day : ) I found out, that I actually need more parts to make the picture more clear.
So the next project is to mix 2 or 3 different puzzles together and make a big one (3000 part). For this I will wait till I am pensioner :D
Look at this to: René Magritte "Ceci n'est pas une pipe"
