Picasso and Onyx Picasso

[mlandscape]

Hello from UK
Looking for some advice on Picasso Clowns. Considering buying the pair in photo.
Being advised that one is Picasso and the other Picasso Onyx.
Its not the name that matters to me as I like them but always like to know exactly what they are.
Any advice would be appreciated
