I got dead ends on some of the other stuff, but most of it looks like bought rather than made items. The boxes and brush on his table would be much easier to pick up from a thrift shop or flea market and throw some gold paint on, than build from scratch.
That mirror really looks like a bought item. The rose pattern is way more complex than needed for five seconds of screen time. The mirror is beveled glass. On the other hand I did find a lot of funky mirrors with "60s wall mirror" but not that one.
