Oh, that precious face. Based on these pictures, I'd say this little one is a white patch classic brown tabby (classic because of the bullseye pattern on the flank). A lot of brown tabbies have black stripes and reddish brown coloring. S/he's absolutely beautiful.
She is gorgeous I agree she looks like a classic marbled type tabby, and but also a bicolor. Such an interesting pattern she has there. The yellow brown areas on her face look more red toned on the pic with her body but I would not call her a calico, some might say caliby or torbie.
