Sparklets Collectors Guide code: SCG/XS-21
Item: ‘The Soul of the Syphon’ Book Marker.
Description: Made by Aerators Ltd to advertise the ‘ “Prana” Sparklet Syphon’. It is made of card.
Size: 123mm high x 64mm wide
Notes: Reverse details the models available together with prices. Probably made in some volume, but I have only seen one other for sale since acquiring my example. This is likely because the item is not durable.
