A postage stamp on the textile art Kalamkari was issued recently. Kalamkari is a speciality of which state?

Kalamkari is a traditional Indian textile art form that literally means 'pen craft' (kalam = pen, kari = work). It involves hand-painting or block-printing on cotton fabric using natural dyes. This art form has been practiced for centuries in the region of Andhra Pradesh, particularly in Srikalahasti and Machilipatnam. The Andhra Pradesh government has been working to preserve and promote this traditional craft, which is why a postage stamp was issued to recognize its cultural significance.
