Canal Zone and Panama articles in Mekeel's Stamp Weekly 1910-1921
by David Zemer
"A Panama Patchwork Revisited" (PDF 20MB)
Volume 1 - The Maduros and their Postcards
By Robert Karrer and Brad Wilde.
Canal Zone and Panama postcards have been popular collectables since before the construction of the canal but until A Panama Patchwork Revisited was published 1989, collectors had lacked an overview of the many different printers, scenes, and types of post cards.
This 240 page book, printed in black and white, solves that problem for the vast majority of cards which were sold under the Maduro family name. There was only one 300-copy printing of the book and at $ 27, it soon sold out presenting a problem for many of the people interested in knowing more about these cards. In order to make their book more accessible Bob Karrer and Brad Wilde have generously permitted the Canal Zone Study Group to place a copy on its website for the use of not only CZSG members but for everyone interested in one of the great engineering feats of the 20th century and the new Republic of Panama.
A Panama Patchwork Revisited is in searchable pdf format and converted to digital format by CZSG member Ralph Weil.
"Stamps Of The Canal Zone" (PDF 3MB)
By WM Evans. M. D. is a specialistic study of the stamps of a dependency of the United States in which
there has ever benn a large measure of philatelic interest.
The The Story of Canal Zone Stamps (PDF 13MB) by Dade and Schay. Ralph Weil has done a remarkable job
and converted Geoffrey Brewster's personal copy of
the Dade-Schay manuscript into searchable text, updated the Scott Numbers to those used today, and embedded color images of stamps and stationery.
Some of the original manuscript, usually hand written tables and drawings, is included in the pdf file as images. The copy that we scanned was the
Brewster photocopy of the Plass version so any notes that appear to be photocopied are from Plass but clearer notes are by Brewster. The original
scan required 262 mb of space but the Weil version is only 13 mb. Because of the large size of the original scanned manuscript, we have not put it
on to our website but if you are interested obtaining a copy please contact David Zeemer and I will invite you to join my "dropbox" where you can download it.
In another labor of love McNabb's Adhesive Postage Stamps of the United States and its Colonies - Canal Zone by George C. McNabb (PDF 8MB)
has also been converted to a searchable pdf document by Ralph Weil. Ralph has again embedded color copies of most of the stamps into the manuscript and updated the Scott
numbers to the present system. The original paper copy came courtesy of Richard Spielberg who worked with Ralph on transcribing it. Richard remembers that he got it from
David Leeds or Dick Salz. The amount of detail McNabb took into account when analyzing overprints will be appreciated by every student of the early Canal Zone stamps.
