家族写真のレトロ旅情ポストカード風イラスト

Transform the uploaded American family or travel photo into a vibrant 1960s screen-printed travel-postcard illustration. Preserve every person’s identity, age, ethnicity, pose, clothing colors and position, along with the exact landmark and camera framing. Simplify the scene into bold shapes with a sun-faded coral, turquoise and mustard palette, coarse ink texture, limited color registration and cheerful mid-century scenic depth. Keep children wholesome and age-appropriate. Do not add stereotypes, change family relationships, include readable text, logos or a watermark.
