Often these are low cost prints for students in developing countries, for example India. They're not counterfeit as such, but the quality is low to keep the price down. Not sure if that's what you got though, as they're all super cheap on Amazon.com. Normally if it's a marketplace seller it'll say where it ships from. Deep Learning RRPs about £50 in the UK. I'm not sure what the print status of the book is. There seems to be an official MIT Press print, but my university library struggled to get a copy through the inter-library loan network because the eBook has the same ISBN.
