Finnegan’s Non-Shenanigans

Mr. Theodore Barnum Finnegan,
He, the finest Colorado emporium
Did retail, 1892, July on the quartodeciman;
Canine, feline, avian, ophidian specimens,
Sturdy kennels, ornate birdcages/cat baskets;
Not ostentatious, but in metal safe a jewel casket,
Heirloom–Haitian; passed through generations.
A sternly optimistic fellow, doughty for sure –
Neighbourhood philanthropy for the poor –
Descendant of G. Washington by repute, sirree;
Finest 'Bird & Dog Fancier' west of Missouri!
