Museo Slab is robust slab serif with Museo's friendliness. Designed by Jos Buivenga, the Museo Slab font family is a perfect match for Museo Sans. The Story of Museo Sans in Jos Buivenga's words: When Museo became a succes I researched some possibilities of other versions. Museo Sans was not that difficult because making a sans out of a (semi) serif is —more or less— cutting off the serifs and adjusting weight, width and contrast. So... I made Museo Sans and while doodling around and fiddling with slab serifs to make Museo Slab I discovered something nice I used to design Calluna1 first. Of course that escapade had a reason. I couldn’t find the right solutions to all Museo Slab’s design hurdles. About one year later —after a radio interview with Aaron and Matt from RBtL2— my interest in Museo Slab got fired up again. Don’t know why, but this time I got it all working. The Museo Slab font family contatains 6 weights & 12 styles. Each font contains approximately 455 glyphs with extensive OpenType features: ligatures, case sensitive forms, proportional & tabular oldstyle figyres, proportional & tabular lining figures, fractions, superiors, inferiors, numerators and denominators.
