Very special offset lithographs on satin paper. These works are made in the U.S.A. by Alechinsky's publisher after printing the hand-signed copies. There is therefore just as much ink on these offsets as on the serial edition. Alechinsky's signature is placed underneath the work and is therefore also printed. The Offset lithographs are from 1978 and made from the original plates. The titles are: Paris Flying Object--Galactic Flying Object--Great Flying Object. The size is 78 x 48 cm in new condition.
