Niuafo'ou Tin Can Mail

This set of 2 values $2.25 and $5.40 were designed in honor of the famous Tin Can Mail.  This was used when ships could not reach the island of Niuafo'ou due to rough shallow waters. 

Boats would put the mail into a specific can (original can featured here) and throw the can overboard.  A swimmer would then swim from the island and grab the can and bring it back.  The process would repeat with mail from the island going to the outside world. 

These denominations of $2.25 and $5.40 are the Registered mail price.

Each stamp size is 38 x 30.56mm, gauge 13.75.
