Pretty map! > What projection is that? It looks like an azimuthal projection. You could produce something similar with an Azimuthal Equidistant or Lambert Azimuthal Equal Area. Compare to your map of Canada. LCC is going to have straight meridians. Notice the increase in curvature of the meridians as you move away from the center meridian in the Pieni Tietosanakirja map. > What arguments should I give to "proj" to reproduce this projection? For Azimuthal Equidistant, you might try something like: +proj=aeqd +lat_0=50 +lon_0=20 or +proj=laea +lat_0=50 +lon_0=20 to get something similar. For these large scale maps, unless there is some particular quantitative objective that would favor a particular projection, picking projections is often a matter of taste.
