Certain collectibles are items that have been collected and preserved over time due to their rarity, historical value, or aesthetic appeal. Stamps (6 letters) are small pieces of paper that are issued by governments or other organizations to indicate payment of a fee or tax. They often feature designs that commemorate important people, places, or events. ART (3 letters) is the expression or application of human creative skill and imagination, typically in a visual form such as painting or sculpture. It can also refer to the product of such activity, which is often considered to have aesthetic or intellectual value.
