new cover on the left, old cover on the right
apparently this was a few years ago, but its still like that cos i just discovered it when buying pratchett books for someone and noticed who the fuck is that guy and where is granny weatherwax, that was not the cover i grew up with
to be clear, this had nothing to do with pratchett himself, who im sure would have been absolutely livid about this
Almost all the modern versions of pre 2000s discworld books are insulting to Josh Kirby, usually cropping out most of his amazing artwork. Its why I wish I had completed my collection of the Mass Print Editions when they were easier to find. Even though they're all falling to bits and yellowed They display the artwork so well. My reccomendation to most big discworld fans would be to get your hands on Josh Kirby's, Discworld Portfolio (a hard find these days, and outrageously priced by those who are selling it) and Paul Kidby's Imaginarium, between these two books you will find all the discworld illustrations a fan could want, including many which are not shown elsewhere, then for the actual books pick up the excellently designed (if somewhat flimsy) collectors editions they have now released with their fantasic lino cut covers and embossed designs. Also see Josh Kirby's In the Garden of Earthly delights for his other sci fi and fantasy illustrations (of which there are many, he was quite prolofic!) including one he did for Ron L Hubbard when he was still a sci fi writer!
holy shit you werent lying, seven hundred and thirty eight dollars
and yeah i always loved those old covers, was fortunate enough to get almost all of them when i was younger (although mine are also pretty battered)
just found some good quality digital versions though, equal rites and my very favourite reaper man
edit: found the discworld portfolio on libgen though im not sure if that link will last
