Ruben Manukyan has participated in numerous exhibitions throughout his career, many of which were not formally documented, as record-keeping during those earlier periods was limited and inconsistent. Because of this, a complete list of his exhibitions is not available today.

However, based on the information and materials that have been preserved and collected over time, a significant body of his exhibition history can still be represented. His work has been shown in various international locations, reflecting a broad artistic presence across different cultural environments.

Among the exhibitions I personally witnessed are those held in Ethiopia, where he exhibited alongside Armenian singers and actors as part of a cultural delegation. I also have records and photographs from some of his earliest known exhibitions, including one of the oldest I am aware of, held in Bulgaria, as well as exhibitions in Beirut.

In addition to documenting these events, I was also present at several of them, where I exhibited my own artworks alongside his. These shared experiences remain an important part of both his artistic legacy and my personal artistic journey.
