This authentic Phillips Petroleum Company bond certificate from 1970s is a collectible printed in red. Issued and cancelled. Once issued to investors, it represented corporate debt for one of America’s most important energy companies.
Phillips Petroleum was founded in 1917 in Bartlesville, Oklahoma by brothers L.E. Phillips and Frank Phillips. The company became a leader in petroleum exploration, refining, and distribution, and introduced the now-iconic Phillips 66 brand, a symbol of American highways and fuel culture.
The company went public with its IPO in 1927, raising capital that fueled decades of growth in oil, gas, and petrochemicals.
By the 1970s, Phillips was a major international player, financing its operations through bonds like this one. Today, Phillips Petroleum is part of ConocoPhillips, one of the world’s largest independent energy companies.
This cancelled bond certificate remains a historical artifact from an era when paper securities symbolized ownership and investment in the global energy boom.
Perfect for collectors of oil industry history, Oklahoma companies, and vintage financial documents, this certificate makes a meaningful addition to any scripophily collection or framed display.
