Kingsford is a brand that makes charcoal briquettes, along with related products, used for grilling. Established in 1920 by Henry Ford, it's still in operation and has a staggering 80% market share in the USA

Ohio Blue Tip might be a reference to the Ohio Blue Tip matches (TIL there's a match museum) from the Ohio Match Company, which was founded in 1895 and was the second oldest match manufacturer in the United States. It went out of business in 1987. The Blue Tip brand is still out there, probably owned by some megacorp
