|Well balanced design: old and modern roadsigns with irregular boulders which is
only natural (despite the E.U.'s regulators wanting to calibrate everything —even
snow flakes if we may believe F'Murr in Le génie des alpages).
This doesn't mean we shouldn't keep an eye on them (the Bulgarian roadsign people), because
they quietly made the number of boulders drop by two! That's how lean sizing often comes, in a

More research is needed.
Some Falling Rock signs from France feature also stones on the ground and
they look perfectly normal.
