Luther Burbank's Phenomenal Berry, Selected Hybrid from Cross of California Dewberry and Common Red Raspberry, 1907

Luther Burbank (1849-1926), an American horticulturalist and author, gained a reputation for selective breeding that yielded more than 800 new fruits, vegetables, flowers, and other plants. By 1906, Burbank's international fame had brought multiple solicitors to his home in Santa Rosa, California, interested in documenting his work. A deal with Minneapolis publisher Dugal Cree resulted in this promotional postcard.
