Catimini is a French children’s brand created in 1972 by Monique and Paul Salmon. It is not clear if the couple also designed the logo, but a recent exhibition of Albert Boton’s work indicated that his typeface Pampam (released in 1974) was the basis for the mark.
Aaron, as it says on our Pampam page, there is a digital version in the works by Albert Boton and Olivier Nineuil, but it has not yet been offered on the retail market. Maybe write to Nineuil and get an update for us. (My attempts have failed.)
