Well in this video the man who found Cheburashka and he hanging up a note with text like "zakryto o schel v zoopark"

Speaking about in/on like on the table=v stolje, you always end a -JE when you responding where a thing/person is.

Why they didn't wrote it here or does it matter?

PS: I'm very sorry that i can't use russian alfabet, please send a PM if you can help me about that.
