Yes it may have been Royal crown, They also embossed their coolers and Royal Crown is also the only known for sure embossed Ideal 35 slider cooler... (smaller than the 55 slider posted here) they are hard to find and quite pricey... I would love to find one of those... Also there is a Squirt embossed slider that was yellow, and a Tru-Aid (VERY Rare) that was embossed (the outer circle embossed on the logo only) and in yellow... Love soda machines and coolers!
