[INTERNATIONAL: TALL SHIPS RACE (2000)]
The Canada Tall Ships stamp(s) (Scott™ #1864-1865), depicted on this first-day cover use (below), was issued on the 19th day of July, 2000, in the last year of the end of the second millennium.

The following list accounts for those who gathered together at the end of the third leg [Boston to Halifax] of what was billed as the Tall Ships race of the Century, which originated from Europe.

The brief (festival) stay-over in Halifax of the visiting crew from these ships started with the release, by Canada Post, of it's Tall Ships definitive stamp(s), actually two, paired end to end, with one slightly different then the other. [a booklet of TEN stamps overall on this first-day cover].

During that time, beginning on the stamps day-of-issue, many of the participating ships "official" cancels were acquired for the privately made cover, while they were berthed around the port city gathering provisions before commencing the final leg of the race back to Europe. Reportedly, only one hand-written cancel was provided by an on duty officer at the time, from the "U.S. BRIG NIAGRA".

Hi savebigblue. When I get home, I'll be glad to share some covers here. BTW, should the first cover image be of tall ships?
