An Austrian artist, Ewald Hotz, was recently contacted by ATcultura too. While I assumed it was a vantiy press, Ewald went through the trouble of obtaining an application form to prove this. A Google search for the show also returns less than promising results.
The application boasts that "there will be approximately 100 (one hundred) for the artists (a book for each one), 200 (two hundred) exemplary ones will be distributed gratuitously in the main museums, universities, libraries and important embassies of different COUNTRIES FROM the WORLD and other institutions that ATcultura as for the best diffusion of the book considers".
For this, you will have to pay $350USD --- a staggering price, which may be better put to use for a vanity show.
I have provided a PDF of the application form for those who want to take a look at it.
