The solution I took for my poster was to have the nuns back facing the audience, saying we know her secret and she does too, and to show the viewers what she holds which is the wine bottle in one hand and the rosary in the other hand, saying that she's balancing both evenly meaning both are important in this play. I went with a specific font type for the text and religious icons as her dress to remind the audience that this play is still a comedic play with the mix of religion.
