Thank you for submitting your item for appraisal. This is a slightly faded offset lithograph reproduction of a hand-colored stone lithograph illustration by John Gould (1804-1881) from his famous publication "A Monograph of the Trochilidae, or Family of Humming-Birds". In this case the helianthea eos golden star frontlet. There is a possibiltiy that this might be a stone lithograph, but if you can see small circles of the printing grid while using a manifying glass it would be an offset reproduction print. An authentic stone lithograph would sell in the low hundreds. I hope the information provided was helpful to you.
