Retro button, likely from the 90's, with a metal Brandenburg Gate over a marbled brown synthetic polymer. Mounted in gilt metal with a clock face border. It looks like a designer logo button, but I am not 100% sure as I haven't identified a maker and it is unmarked. Measuring about 1 & 13/16" across in good condition, there is some general wear to the finish on the metal.

Thanks for looking, and be sure to check my store for more great old buttons!
