Tina is a fairly mysterious entity created by a company called Replitoy. She is the same size as Pippa, but her legs are straight molded plastic with no knee joint.

Like Pippa, Tina Mod took on some of Dawn's outfits; Dawn's Raincheck and also Glimmering Stardust are two I've seen packaged. Some of her outfits also may have been created from the same patterns as some Dawn outfits.

Tina is not terribly good quality herself, but has quite a nice face The outfits are generally a good buy for Pippa collectors, often being of similar quality to Pippa outfits.

I don't have an exact date for Tina, but I think she's probably 1972/73 because of the Dawn outfit connection.
