Do you know of any references for the local provisional "Blockade" issues
of Indonesia that were used intra-island just prior to those printed in
Vienna, Austria. Also, do you know of any references for the Japanese and
local overprinted stamps of Netherlands Indies from WWII and prior to
independence being recognized? These issues are depicted and briefly
footnoted in Michel.
