Hand cast and chrome or nickle plated, these mascots adorned the bonnets of many cars in the 1920' and 30's.  They were made by A.E. Lejeune and sold for 3 guineas in 1923.  One such mascot replaced the 'Spirit of Ecstacy' statue on film and stage actor Jack Buchanan's Rolls Royce!
At least two other Bonzo mascots were made by the Lejeune company.  The one on the left has a chrome / nickel finish & the one on the right is brassed.
 

The company who originally made these mascots is continues in business today, and still have the original casting moulds.  They will cast a new 'original' on request, with a chrome, nickel, or even a bronze finish!  If you'd like one, contact:
