I got both these postcards in 1995 before the casino explosion in 2002 and before the Chinese takeover.
China took over British Hong Kong in 1997, then Portuguese Macau in 1999.
The top postcard is pre 1970's and the bottom card shows the 1970's expansion.
Look up Lisboa casino in Wikipedia for update photo today.

Asking $5 postpaid for both.
Post sold sign and email me. Thanks.
