Patti K. Hoss initiated the formation of Creative Offsprings in 1985 to preserve and proliferate the artwork of Della Taylor Hoss. Della's artwork featured Yosemite, the Bristlecone Pines of the White Mountains, east of  Sierra, and Stanford University. Della lived in Yosemite with her husband Herman and son Peter from 1928 to 1942. From 1942 until her death in 1997, Della lived in Palo Alto. Patti K. Hoss was married to Peter T. Hoss from 1959 until her death in 2001. Marino Hoss and Vincent Hoss are sons of Peter T. Hoss and grandsons of Della. Martino is a fine artist located in Seattle specializing in landscape serigraphs, pastels on copper, and paintings. VInce is an architect with BFGC, an architecture firm in Bakersfield, California.

In 1932 (reprinted in 1948) Della illustrated a book entitled "Trees of Yosemite" written by Mary Curry Tresidder. Mary was the daughter of David A. Curry, founder of Camp Curry in Yosemite, and wife of Don Tresidder, CEO of the Yosemite Park and Curry Co., who became President of Stanford University in 1942. The illustrations were produced from linocuts crated by Della.

Martino and Vince located the original linoleum blocks used by Della for "Trees in Yosemite" and printed twelve prints under the title "Remembering the Trees." The prints are being sold through the Ansel Adams Gallery in Yosemite and the Ahwahnee Hotel. In 1996 Martino and Della shared a two-generation printmaking exposition at the Ansel Adams Gallery in Yosemite.

In 1970 Della produced a series of nineteen pencil drawings of the Bristlecone Pines in the White Mountains, one mountain range east of the Sierra. They are believed to be the oldest living trees in the world, over 4,500 years old. Michael Osborne Design of San Francisco produced digital prints of Della's drawings.

Creative Offspring markets the prints featured in "Remembering the Trees" and the Bristlecone Pine prints. They can be ordered on this website.

In 2011 Peter T. Hoss published a book entitled "Born in Yosemite," a personalized history of 75 years in Yosemite, which he wrote between 1999 and 2011. The book is being marketed by Creative Offsprings from this website. On the cover of the book is a color woodcut by Della, one of four created by Della. Martino has now created six more colored prints from Della's linoleum blocks. The woodcut on the cover captures the essence of Yosemite, described in "Born in Yosemite."
