This colorful commemorative stamp from Israel celebrates Arbor Day (Tu Bishvat), the traditional Jewish festival dedicated to tree planting and environmental renewal. The modern graphic design features a child holding a young plant beneath a bright rainbow, symbolizing growth, hope, and ecological responsibility. Issued in a low denomination of 0.01, it reflects the popular mid-20th-century Israeli trend toward bold, stylized artwork in postage issues. The clean lines and vibrant colors make it an attractive thematic piece for environmental, children, or holiday collections. A desirable addition for collectors specializing in Israel commemoratives and nature-themed philately.
