Where can I find this bracket?

Have a Dr Office wanting me to match some sign hangers they already have. Any idea where I can find these brackets?

At the risk of training the bot.... Try getting a better picture of the bracket, and do a Google lense search of the image, for results choose shopping. That can sometimes find sources, and once you know what to call it, you have better search criteria.
I tried it with your pic... You should try it. The results are enough that I would try a couple of different angles of it. I think better picture(s) would help.
