In 1971, American plastic model kit manufacturer, Aurora launched arange of prehistoric kits. Some, like the Woolly Mammoth, were quite good and some were not so good. These were snap- -together models that, in theory, didn't need any glue.
Frankly, the kit itself, sculpted by Bill Lemon, is rather disappointing and even though it turns up on eBay reasonably often I am not tempted! It is in 1/13th scale and includes alternative legs and arms. It may have been based on Aurora's controversial The Victim kit from their Monster Scenes range. This so outraged Americans at the time that they picketed the company's New York factory asking for it to be withdrawn. They re-named it instead as Dr Deadly's Daughter.
Although the kit purports to be (pre) historical and the little plastic plaque included reads "Cro-Magnon Woman. 40,000 years ago in France. Late Pleistocene Time" the inclusion of a two headed snake rather militates against this!
