Do trumpet display stand designs for stage or marching bands exist?

[Moganza]

I have attended multiple musical nights and marching band programs but haven’t seen a trumpet stand. How different from the images on the internet?

Do you mean a stand to put your trumpet on whilst not playing? There are plenty of those available. Or a clip to put music on whilst marching? I think they can be called a lyre? It sounds like are maybe not in the UK so shop recommendations may not help.
