I've painted the movement, shapes, and atmosphere of clouds. I've printed postcards of the sky paintings I created for a previous exhibition. This is a set of 3. Two of the three postcards (the postcards in the 3rd and 4th photos) were printed by a printing company and have a smoother texture than those printed at home. Printed with inkjet ink, so they are vulnerable to water, please be careful. You can use them as regular postcards by attaching a stamp. Size: 100 x 148mm Thickness: About the same as a standard postcard The colors are as close to the originals as possible, but the colors may differ from the actual product depending on your mobile phone or PC monitor environment. Please understand. Thank you for looking.
