A hateful “art’’ installation featuring a mock street sign reading, “F–k Israel Ln” and a “Hamas Lover” poster was exhibited on taxpayer-funded Governors Island during a weekend family Halloween event. The crude “unauthorized” display excoriated the Jewish state, including with another poster that read it’s “beyond the pale” for Israel to exist and lauded US-designated terror groups, according to images obtained by The Post. The outside of the cabin housing the installation ironically had a sign on it that said, “Revive Humanity Now.”
