ok, the first link doesnt work but the second does
anyone please jump in if I make any incorrect evaluation here. While this carpet may have been produced in afghanistan, many carpets are made in india, and other with similar design nowadays. There were a lot of these also coming from pakistan as well.
The general design is accepted as a "turkman motif" This design is seen in chaudor, ersari, and yomud carpets. Typical keyword search would be tekke. The gul which some refer to as an elephant footprint is also found in traditional afghan rugs, however usually feature less overall colors and are usually fatter and rounder. In this case, it would be safe to say that either a "tauk noska gul" or maybe even a "temerchin gul" which often have alternating colored quadrants within a squashed octogon featuring reds and ivory. This bukhara type of genre, as many tribal rugs are among the more technically assessed carpets, down to the z and s spun wool, veggie dyes etc.
A really, Really good book for understanding these carpets comes from peter Stone called "Tribal and village rugs"
