I have overridden the first link and need to remove the second one "A Kings Speech by Marlena Hebenstrait" 

because all my Titles are in the description so what I'd like to see is only "Back to the Gallery" 

thanks for your time. A Kings Speech by Marlena

a.ProductItem-nav-breadcrumb-link:last-child {
    display: none;
}
span.ProductItem-nav-breadcrumb-separator {
    display: none;
}
