It should be noted that cards of the same design (or mirror-images) bear different identifying text. The same design was often used for 'sister' ships, or minor changes such as the cloud formations made.
Following the withdrawal of Tokyo as host, remaining stocks of postcards were overprinted with a decorative screen to obliterate the Olympic text.
The density of ink used for obliteration of the Olympic text is variable, the results range from a light printing alloqing the text to be easily read, to a heavy printing where the Olympic text is almost undetectable.
The N.Y.K. fleet contained a number of groups of 'sister' ships, built to the same designs. The postcards of the vessels were produced from artwork, and the individual artwork of a type of vessel has been used with minor changes or manipulation (clouds in the sky, mirror image, etc.) to represent more than one ship, by adding a unique name and details of a specific vessel. For some postcards, it would appear that the colour 'generic' card may have been printed as a bulk lot with the individual ship details added as a secondary process.
