Port of Spain

While I credit this to Kyle Mathis, as Difford's Guide says, this itself may be a riff on a similar drink. Given the similar date of origin and this drink's use of rye rather than mezcal, allspice dram, and grenadine rather than orgeat, I am inclined to consider it at least a very distinctive variant if not an original which just happens to have some similarities.

In any case, I'm a big fan of high Angostura bitters cocktails and this is no exception.
