This is a unique square ashtray by Sascha Brastoff. It is done in a lime green, orange, white and gold coloring. It measures 5 1/2" by 5 1/2". On the back in gold, it is marked SASCHA B with an R in a circle. This would date this ashtray from between 1962 - 1973. It is also numbered on the back 03. It is free of cracks and chips and would make an awesome piece to add to your collection.
