Monsieur Lavanti at Victoria Concert Hall, West Hartlepool

This time I have a fairly early poster from the Victoria Concert Hall in West Hartlepool, which includes a performance from Monsieur Lavanti “Champion Juggler” for the week of May 2, 1870:

Unfortunately I can’t find anything about this chap, or any suggestion of what championship he might be claiming to have won. Does anyone out there have any leads?
