This is one of two miniature art prints I have featuring the distinctive style of Vincente Cristellys (1898-1970). Not much is known about the artist except he was born in Spain. The other print is listed here: https://www.rubylane.com/item/274812-8504/1950s-French-Fashion-Beauty-Red-x22Parisiennex22
This "Parisienne" series was produced by Éditions d'Art by Yvon, a famous and prolific postcard publisher in Paris. Hence, I often refer to these as postcards, but technically, they aren't. No postal notations verso and these mini prints are an in between size from antique to modern postcards, measuring 4-1/8 inches wide and 5.75 inches tall. Unused and in overall very good vintage condition; just the slightest hints of wear on the corners.
The last photo shows you a couple more of Cristellys' designs, to give you a better idea as to whether or not you'd like to start a collection of his work. I've been lucky to get my hands on these in the past; it doesn't take long to figure out which prints are harder to find!
