Introduction to Guatemala Philately

Guatemala Fakes and Forgeries

Collecting the stamps of Guatemala is an interesting and potentially complex challenge, and collectors of the country are helped by a large body of available information. El Quetzal editor and former International Society of Guatemala Collectors (ISGC) president David Reitsema has added to this information by writing three articles to assist ISGC members and other ISGC website visitors distinguish between genuine stamps and fakes and forgeries of the early Guatemala stamps (Scott 1-10). Follow the links below to view and download these informative articles.

These are the first in a series of articles about Guatemala Fakes and Forgeries which will continue to be posted periodically on the website.

Jonza Documents Available for Member Download

Long-time ISGC member Jack Jonza has collected nearly 150 articles and clippings that have information of interest to Guatemala collectors. The articles come from many sources, including magazines that have not been published in many years. These have now been scanned and indexed, and may currently be viewed and downloaded in the Document Library by members after logging in. The first PDF in the folder was prepared from a spreadsheet containing information on the documents, including author, publication, publication date, catalog numbers,etc. Download it, then use the links in the titles to go to the individual documents that interest you. 

2019 Annual Meeting To Be Held at RMSS

The ISGC will hold its next annual meeting on the last weekend of May, 2019 at the Rocky Mountain Stamp Show in Denver, Colorado.

The show will feature a pan-Latin American emphasis. Joining the ISGC will be MEPSI, which is also holding its annual meeting at the show. Other Latin American philatelic societies have expressed their intention to be in attendance and involved in various ways.

The ISGC has informally reserved 50 exhibit frames and we urge all members to get their exhibit applications in early (mid-October!). MEPSI and the Peru society also have each requested 50 frames. There are expected to be at least 360 exhibit frames and despite that number the demand will exceed available frames. At this time, members who have indicated they intend to present exhibits featuring Guatemalan material include Michael Bloom (two exhibits), Tim Bartshe, and Jaime Marckwordt.

There will be seminars throughout the show on Latin American philatelic subjects presented by invited specialists and additional presentations during the show.

Make hotel reservations early, there are not a lot of rooms available at the hotel venue and they will go quickly. The society will have social events planned and more details will be forthcoming.
