This "PRIVATE AREA - No trespassing" sign is located in a somewhat well-off neighborhood. The houses nearby are very well maintained and clean, which stands in a striking contrast to the dilapidated condition of this sign.
The "PRIVATE AREA - No trespassing" is a common sign in Finland, used to signal various things, but in this context the aim is probably to stop passers by to use the interior yard as a shortcut. (As my former boss noted, if you are in an unfamiliar area, these signs are great because they tell you where the best shortcuts are! There would be no need to forbid them if they were not normally used by quite a lot.)
But here we note that the housing community does not seem to be too interested in signaling that the route should not be used. Looking around at the spot shows that they clearly are interested in maintaining the area, but it feels as if they are ignoring this sign in particular. To me this transforms the message into something like "Walking through here is technically forbidden, but we don't care that much."
So this is a fine example where the message of the signal is affected not only by the sign vessel, but the condition of the sign vessel relative to the environment! As a sort of opposite example, the following sign states "Nostopaikka" (lit. "Lifting spot") and marks a spot that needs to be kept free for bit fire trucks that need to lift ladders and such. The fencing it has been attached to is dilapidated, but the sign shines bright.
