Our earliest samples from Russia (children and men signs) were recorded in the year 2000.
We had to wait for 16 years before one of our team on the road eventually came back
with a Falling Rock Sign from that country.
The same constellation can be found in several satellite countries of Russia
like Armenia, Kazachstan.
So now we have a Russian group
for each kind of warning sign in the collection. There is more freedom in the rock signs, however.
The satellites can grow several (sometimes many like f.e. Armenia) variations on the rock signs and this
does not happen with Men at Work and Children's Crossings which are all alike over the entire area.
