Hi Blair,
why the either or?
Puleguso as a technique was used by Beranek with various degrees of finesse, such as pieces for AKA, designed by Lichtagova, Fuchsova and others in the 1940's, and some by Emanuel Beranek himself. It was used again to make copies of Beranek's own designs in the 1990's ie pattern numbers 9260 and 9279.
Regards,
Marcus
