Thank you, everyone, for your opinion and knowledge of the TOS.
So I guess I will use these types of images whenever possible.
After I posted this thread, I visited the Palace of Mafra with the family.
Needless to say, I bought some postcards at the palace and took a picture of them with their specific depiction.
I’ll share them with you:
I’ll send two of these tomorrow from the Post Office next to the palace.
I hope you and the postcard recipients like the pictures.
