An iconic PH5 limited edition 10 year jubilee model from 1968. 
The PH5 was presented in 1958 at Illums Bolighus in Copenhagen by its designer Poul Henningsen
In 1968 they celebrated the 10 year jubilee by reproducing the model from 1959 which had undergone a couple of design changes in the first year of production from 1958. 
This color which I would describe as a light pale blue was only used on this 10 year jubilee model. 
This iconic chandelier lamp is in great condition and is very straight but it is over 50 years old and does have some age related wear and patina.
