This shop is a family business created 'for' (czy masz na mysli ...dla mojego dziadka?) my grandfather in 1920 in Cuenca (Spain). 'It' (NIE it, ale 'its') main function is the sale of shoes.
During 'that' (to znaczy ktorego?) time the company has grown and extended the 'offert' (popraw). At the moment we are one of the most important supplierS of exclusive shoes.
