If you can scan that passport page or take a digital picture of it and send it by email to email@example.com, I will look at it and try to find out. Thaks.
No problem! I hope I will be able to help.
Thank you for your question and welcome to Just Answer.
On the right (page #15) you will see Thailand's stamps. I was in Thailand last October and can confirm this is how it still looks, a triangle and a rectangle. The outer edges are numbers, and on the insides it gives says "Bangkok, Thailand" or other city.
Here is a picture of someone who has been in and out of Saudi Arabia. You'll notice a crossing of two swords and a tree in both sides.
I hope this information has helped. If so, please don't forget to "Accept" my answer.
