This isn't Giuseppe Garibaldi it's an early draft of Duca Degli Abruzzi. Giuseppe Garibaldi has a tattoo on her chest, has a smaller but and doesn't have a prosthetic arm. Duca Degli Abruzzi on the other hand has larger boobs, no tattoos and a prosthetic arm. This image has more in common with Duca Degli Abruzzi than Giuseppe Garibaldi, there's only the hair that matches.
