In December 1943, following the success of the premiere of Madre borrada, Amira de la Rosa founded an eponymous stage group with professional and amateur actors. The group was based at the Murillo Theater in Barranquilla and toured other cities on the Caribbean coast of Colombia such as Cartagena and Santa Marta, where it was very much applauded. This group was active until 1945. In an interview with Alfredo de la Espriella published in Marsolaire, Amira said that it was through theater that she found a means of expression and discovered a taste for communicating feelings and emotions. She began by writing short plays that were performed by the students at her school, but it was in Spain that this experience matured and she began to write for more demanding audiences.
