The central image (enlarged below) is an illustration of the whole site - comprising the factory on the right, Gillies's own home (Cardy House) at the top, Cardy Cottage on the left and the bowling green in the centre. The net factory was originally smaller than shown below and was extended north some years after its 1867 construction. Note the distinctive fish-shaped roof vents which can be seen on the factory roof.
The poster was probably created around 1885. Further detail from the artwork can be seen below - including a traditionally clad fisher woman and man. The woman is pictured with an east coast style creel. Solidly woven at the sides with an accompanying 'skull' (a circular frame basket that sat on top of the creel) this was all made of salt water resistant cane. When full these could weigh up to 55kg and a head strap was used in order to support the weight.
Of course, we now know that the business declined not long after the creation of the poster. However, the illustration continues to be enjoyed as a piece of art in its own right.
