Samuel Dixon of Dublin was made famous by his sets of embossed bird and flower pictures (issued between 1748 and 1755). Dixon used a technique which he called basso relievo, in which parts of the design were raised by means of moulds impressed from the back and then coloured in gouache - similar to an early form of raised papier mache decoration.
The present pictures are likely to have come from one of Dixon's sets of flower pictures of 1748, which were issued in sets of twelve. Unlike with Dixon's larger bird and flower pictures there are no recorded examples of flower pictures such as this bearing his label.It is probable that the work was carried out by an apprentice.
