These come from a full sheet of 50 charity labels (also known as Cinderella stamps) that were used in fundraising for Cal Farley’s Boys Ranch, near Amarillo, Texas. The facility, now operating as "a residential community open to at-risk children ages 5 to 18," opened in 1939.
My guess is that these seals date to the 1960s. Many different varieties supporting Cal Farley's have been printed over the decades. (They're all over eBay, if you want some.) I'm not sure if there's much of a market for collecting the most common Cinderella stamps, but there are definitely folks who collect rare ones.
These Cal Farley labels include the phrases "It's Where You're Going That Counts" and "It's Easy To Smile When Someone Cares."
Printed across the bottom of the sheet is:
GIVING HOMELESS BOYS A SHIRT TAIL TO HANG ONTO
YOUR GIFT IS DEDUCTIBLE FOR INCOME TAX PURPOSES
Cal Farley (1895-1967) was a World War I veteran, semi-pro baseball player, professional wrestler and businessman who has been called "America's Greatest Foster Father."
In addition to founding Boys Ranch, he assisted C.C. "Bus" Dugger with the launch of Kids, Incorporated, a youth sports association, in 1945. (Dugger died a few weeks ago at age 96.)
The Cal Farley organization's ongoing outreach and involvement also includes the Genie Farley Harriman Center for Women & Children. It was formerly known as Girlstown U.S.A. According to Cal Farley website:
"In 1987, Cal Farley’s welcomed Girlstown, U.S.A. into its family of services. Founded in 1949, Girlstown offered girls a safe shelter from life’s storms. By the mid-1990s, Boys Ranch had integrated girls into campus life and, in June 2012, the Whiteface, Texas, campus became home to the Genie Farley Harriman Center for Women & Children. The CWC provides single adult mothers a safe living environment while they transition to independent living."There is also the Boys Ranch Independent School District, which includes an elementary, middle and high school and "was established in 1941 through legislative action. It is considered a 'special purpose' independent school district of Texas, funded in part through annual contributions from Cal Farley's and in part through state and federal education funding mechanisms."
