Here are a few more (don't think they are duplicates).
First is an item from INDIA, issued in 2009(ish) to honor Indira Gandhi. This technically is NOT an aerogramme, but the format is the same, and the concept is the same, just for local India mail.

Next an item from Indonesia. Year unknown as it exceeds my catalogs).

Here is one from Liberia 1956 item. Catalog (H&G) F-G-5g. Watermark "V".

Next, an 1967 LIBYA item. White address blocked-out by me, NOT part of envelope design.

and... finally for this post... An unusual item (for me) is this
item from a short lived Peoples Republic of Kampuchea which existed between 1979 thru 1989. Look up history if need be. This item was issued in 1984 for Los Angeles Olympics. The white (clear) address section is part of envelope this time.

Hope these were of interest. Gotta go do some yard work. Maybe a few later...
