Njeri Illustrated. Your City... Illustrated. This greeting card features an illustration of the Serpentine Lido in Hyde Park. Inspiration: As Hyde Park is one of my favourite parks to visit, I enjoyed creating this fun illustration of the Serpentine Lido.

The size of the greeting card is A6 (15.0 cm x 10.5 cm). My cards are inspired by London, designed and printed in the UK. Please get in touch for our full price list, T&Cs, and to request a sample!
