These two dolls advertised the Estey Organ Company. I imagine they were printed around 1900, give or take 5 years either direction.
These same dolls were also used by the McLaughlin Coffee Company and others. That would be an interesting item to collect; all of the dolls from the different manufacturers.
Sadly there's never any artist information given about these old advertising paper dolls.

The Estey Organ Company was founded by Jacob Estey when he bought out a Brattleboro, Vermont manufacturing business in 1852. The company went on to become the largest manufacturer of organs in the United States. The original company had been founded in 1846. It employed more than 500 people and its high-quality items were sold as far away as Africa, Great Britain, Australia and New Zealand. Around 500,000 to 520,000 reed organs, or 'pump organs' as some term them, were built between 1846 and 1955. (SOURCE: Wikipedia)

UPDATE: From reader WJY:
Your dolls were probably made between August 1898, the end of fighting of the Spanish American War, and December 1898, when the Treaty of Paris was signed, which resulted in the annexation of Guam, Puerto Rico, the Phillipines, ended the occupation of Cuba, and recognized Cuban independence.
