China $3/4c Postcard, 'Temporarily Used for $3' 暂叁 售圓 $3.00

I have searched extensively on the internet to find an example of  this postcard.  I finally located two used copies and these were from Interasia Auctions sales in 2012 (cards shown below).  Those have special international usage and are pricey items.  Since this issue type of temporarily overprinted postal stationery cards had limited usage, with the dates on the used ones I found, at least we know they were used at the end of April through the beginning of May 1945.  That does not support my guess-imate above in a previous post of possible usage dates of 1946-47 (again, that was only an estimate).  I have been searching a long time and found only these two Interasia Auction listings and nowhere found any reference to any unused copies.

If anyone has a Higgins & Gage Catalog covering China or the Han Catalog of Chinese Postal Stationery, would you kindly provide the catalog information for these $3 Temporarily Surcharged 4¢ Sun Yat-sen Postal Stationery Cards?  If possible a picture of a catalog page would be most useful.  Thank you very much.
