The Inspiration for the Design
What you should look for
As with all the values of this issue, look for Columbian Expo cancels or on a Columbian Expo cover, they increase the value of the stamp or cover. Any stamp is more desirable with a clean cancel, preferably a town cancel, heavy cancels can detract from the value and are common on this value.
Varieties to look for
The color ranges from Slate Blue to Dull Slate Blue. There are the occasional double transfers.
Occasionally postmarks from states that had tiny amounts of mail in this year can add to the value. This is particularly true of Alaska and the Territories. For a list of the number of stamps issued by each state in the year ending 30th June 1894 click here.
The Essay's and Proofs
Large multiples, such as the one above, are rare in this value
The Columbus Expo was not all about large exhibition halls and grand boulevards. In between
on a street called the 'Midway' were scores of smaller booths, tents and the like. Shown
above is the Submarine Diving Exhibit, sans water.
