 * There's a portrait of her in the Agreste mansion that resembles Gustav Klimt's Portrait of Adele Bloch-Bauer I, commonly known as The Woman in Gold.
 * The image of her used as Adrien's computer background is actually a real-life photo of voice actress Tara Strong, with the top changed from magenta to blue and Mrs. Agreste's face edited over Tara's face.
 * A picture of her is inside of the Moth Miraculous, which is currently owned by Hawk Moth.
 * Inside a safe-box, Gabriel keeps the Peacock Miraculous and a booklet that reads 'TIBET' in big green letters, in front of a picture of her.
 * If you have watched Tokyo Ghoul, Attack on Titan, Full Metal Alchemist, Ano Hana, and/or a few other anime, you will see that characters with the hairstyle shown in Mrs. Agreste's picture die.
