Slogan Cancels On Canal Zone Covers

Here is a set of really neat slogan cancels on 1938 Air Mail covers posted in Cristobal, C.Z. I have expanded one to show a little more detail but they all include a map of the area, with the Atlantic and Pacific labelled. What changes, is the actual slogan at the bottom of the map.

These three read

The Panama Canal: To World Markets
The Panama Canal: Shortens Sea Routes
The Panama Canal: Speeds World Commerce

Does anyone know if these three are all that exist in this series or are there others that might be hunted down.

I like these from so many angles, the biggest being the interesting slogans and use of the map.

I am a bit jealous. I do not have a Hotel Washington cover . . . yet. For many years it was THE best hotel in the country.

When I get home I will look through my CZSG books and see if they have cataloged them.

I like the stamp as well. The hill on the right is called Gold Hill, and the hill on the left is called Contractor's hill (though they were both part of the same hill before the canal was dug out between them). I have spent may a day looking down from Contractor's hill and watching Canal traffic pass through the cut. Gold hill was re-shaped in the 1990's and heavily fortified to prevent further landslides.

I could go on . . .

Smauggie, if you want to get in touch by email, I do have a fourth Hotel Washington cover to the same address, with a repeat of one of the slogans which is yours if you want it. We can work out a trade or some such.

I have not yet found my book, but I did take a look at my covers, and came up with the same three slogans (and no additional ones).

With your knowledge of the area, this might also be of interest to you. The hand written envelope is not hotel stationery, but it is company stationery of some sort. On the reverse, a company name is printed. This might be, I suppose, a local company or a Branch Office of a larger firm, the United Fruit Company.

However, what Great White Fleet refers to is completely beyond me.

I don't actively collect cancels, but this also caught my eye in the past. I was told that this series of cancels has 10 types, although I never saw a complete list. I acquired a bunch of these cancelled on blocks of 4 (not on cover) a few years back. Don't know where I archived them, but one slogan that you don't have is

"GATEWAY OF WORLD TRADE"

You might want to check with the Canal Zone Study Group, an APS affiliate.

As usual SCF comes up with the answers...

Great white fleet refers to all the vessels
in the United Fruit flotilla plying the
commercial trading routes. (all hulls were painted white)

A picture of one is here,
(and I think wiki lists all ship names somewhere)

Another is

"Gateway of world trade"

This is all I needed! Something else that I am now going to have to keep an eye out for. Slogan cancels - 1938 - Canal Zone. Must be about #156 on my list of things I want to complete a set.

Thanks for all the info and I am going to print a copy of the white freighter to display though I won't, I won't, I won't start another theme related to that.

Want to see another Great Cover Theme (Incomplete)? I shall post one titled Northwest Passage Post Offices later today.
