This is how all beef was aged (usually in halves or quarters) back in
the days before "Cryovac". The Cryovac process has accomplished two things very well; it allows the processor or jobber to hold the product much longer without darkening from air exposure and allows the consumer to pay beef prices for water weight.
As a teenager working in the butcher shop a Sirloin was always kept laying on the top shelf in the walk-in for family use. When steaks were wanted we pulled it down cut the steaks to desired thickness then trimmed off the green edges. Steaks with fantastic flavor and cutable with a fork.
