Height: 20cm, Width: 25cm, Thickness: Approximately 4mm I've been drawing a lot to improve my artistic skills. I'm selling these because I've run out of space to display them. I hope someone will appreciate them. I will package them with waterproof materials and cushioning for shipping. *Please note that the marks on the back are not dirt, but rather the acrylic paint used for the artwork. Thank you for your understanding.
