The classic pickled punk, floating in a jar of preserving fluid, became most popular during the golden age of sideshows and experienced a great resurgence in the 1950s and 1960s. During that era many punks were linked to drug abuse, at least in the banner lines outside. Several sideshows featured extensive punk displays – some authentic and others gaffed (faked). Following this era, laws began to restrict the display of punks. To complicate matters, laws differed from state to state, making traveling displays almost impossible. Furthermore, the question of whether punks qualify as "human remains" further complicates the laws.
