"Slavin was billed as world champion and holder of the Richard K Fox Police Gazette Championship belt"
25th November 1896:
"The Mirror of Life stated Peter Jackson is the World Heavyweight Champion"
By lineage rights the Police Gazette title belonged to Sullivan, since he beat Kilrain for it. From thence, Corbett. Then again, Fox never took to Sullivan, so he likely stripped him.
