One of my hobbies is looking up old prices in the BLS CPI calculator to see what they would cost today (March 2026 is the latest data.) The June 1940 photograph along Hwy 1 in Maryland had $0.05 hotdogs ($1.17) and $0.10 burgers ($2.34). The Feb 1959 photograph from the NYC diner advertises a $0.45 burger ($5.14) and probably a $0.75 steak sandwich ($8.57)
