Found in an obscure Spanish arts ‘zine from the late 1987, newly on Archive.org. Punto y Coma, No. 8 had a long section on Lovecraft. Several articles but basic introductory stuff, by the look of it. Yet there is this unusual map, which attempted to trace the movements of Abdul Alhazred, the mad poet.

I seem to recall there’s at least one chunky novel that tells the ‘life story of Alhazred’, and I guess it probably has maps. But this map may interest some.
