Sinorama took part in planning the exhibition and collecting materials for it, but we found ourselves hampered by the fact that early products of most manufacturers have been lost and written documents such as catalogues and advertisements are also lacking.
在本刊參與策劃蒐集的過程中，卻苦於大多數廠家的早期產品多已佚失，型錄廣告等文獻亦付闕如。
