This seller has a number of small paper items up right now, all cited as being older than they are. These two small seals were produced by Gibson and sold in the early 1920s in a boxed set of twenty. (See the top of page 264 for the set as well as the other I feel represent the very best designs Gibson made.) Complete Gibson boxed sets are quite hot now, and have been for some time. They were made in significantly smaller quantities than the slide boxes Dennison produced.
