Well we are all human and make typos. If you click on the picture and bring it larger, you would have noticed it says 1997 on the card.

About Epilog Laser
Headquartered in Golden, Colorado, Epilog Laser was created in 1988 to bring flying-optics based CO2 laser engraving systems to both commercial distributors, small business owners and the home craftsman.

CO2 laser engraving systems can cut and engrave into wood, acrylic, plastic and many other materials. These types of systems also do well on stainless steel and coated metals.
Due to the increased need for convenient metal marking solutions, Epilog Laser expanded its product line to offer a fiber laser system that allows users to mark directly on metal surfaces including titanium, steel, aluminum, carbide, alloys, brass, and more.

The company is now the leader in designing and manufacturing flying optics based CO2 and fiber laser systems.

Anyone of us could make the mistake of 1977 vs 1997, but you're right, there should have been some proof-reading before being published.
