I order this chalk board poster for Govind's first birthday party. And all guests liked it. It is being appreciated by other parents too.
I got it from amazon. You can check out this website for further details on various themes, sizes, formats and backgrounds. You can get it in poster form or even hard board form. They are very flexible and very approachable. First they will send a google form for filling in the details and once the order is placed they will contact you for further modifications over whatsapp and phone also.
