Los 402
1941, Bang Pa-In Palace issue, 31 mostly bi-coloured imperforated essays in denomination 2 st. (4), 15 st. (15) and 10 baht (12), ungummed, hinged on pages. These essais were printed by the Royal Dutch Printers "De Unie" in Batavia, Netherlands East Indies as proposal for the new issue; only few did survive, few similar items exist in different sizes and denominations. An exceedingly rare group; these essais are not recorded in Anatchai Rattakul study of Thai Mail 1836-1943 (only plate proofs in the issued design being illustrated) and not found in any of the important Thailand stamp collections of the last few decades.
