Why don't we see real photos of clelia Teresa vigano?

Clelia Teresa Viganò, an Italian religious figure and founder of the Congregation of the Daughters of the Sacred Heart, lived in the 19th century, a time when Photography was not as widespread as it is today. Additionally, many religious figures from that era did not prioritize public exposure or documentation of their likenesses, focusing instead on their spiritual missions. As a result, there are limited historical photographs or portraits of her available.
