Below are selected Buenos Aires 24 images. Here is a link to the main Buenos Aires Numeral Postmarks page. Illustrated below left is a 5c1Et with a somewhat worn impression. Below are several Buenos Aires 24 specimens. The specimen in the first row, also shown in inverse, is a peculiar early postmark. It has a smaller diameter than most Buenos Aires numeral postmarks. The two specimens on the bottom row (5c1Et on the left, 5c1CLt on the right) show two more variations of this postmark.
