Hello there,
we would like to let you know that the original name of so-called Slant font is New Zelek and it was designed in 1974. After 40 years of crazy usage it gets a digital adaptation which was consulted and approved by its original author, Bronisław Zelek.(Check out bronislawzelek.com)
New Zelek Pro is available at threedotstype.com.

Could you remove Slant font from your website due to copyright? Thanks!
