I've reviewed them all at Tobacco Reviews. Look under Standard Tobacco Company of Pennsylvania for them. Here's my review of the 1921:
The Virginias are very grassy along with a hint of toast, earth, and wood. In a secondary role is the spicy, raisiny, figgy perique. The sweet rum topping is lightly applied. The nic-hit is a shade past the mild level. Won’t bite, and has no dull spots, but can get slightly warm on the tongue if puffed fast. Burns clean at a moderate rate with a very consistent flavor. It does need a few relights, but leaves little dampness in the bowl. Can burn to ash. The pleasant after taste and room notes will linger a little. Can be an all day smoke.
