Colonial, Imperial
Imperial's Colonial candlesticks are found in two sizes; 7 inch and 9 inch with an octgonal base. They are sometimes called Delta Base. This pair in smoke sold for $90 in 2003; a similar pair in smoke sold for $110 in 1999 and another in 2012 for $70. The mug is distinguished from similar mugs by it's octagonal base. Mugs listed as Colonial sell in the $15 to $20 range (only marigold).
Imperial's Colonial vase is very similar to their Flute (note the shaping around the collar base) as well as several other maker's vases. This 12-inch marigold example sold for $35 in 2010.
