Alternative fronts
The reward cards shown above all read 'With the Compliments of the Proprietors of Cadbury's Cocoa', over two lines on the front. A later issue was made, probably in the 1920's or 1930's which reads 'With the Compliments of Cadbury Bros. Ltd' on one line on the front. On the reverse of the card the words 'REWARD CARD' is also different with the font used being in a 1930's style. For comparison of the two issues, see the Pine Hawkmoth cards below.

I am unaware of any details as to a re-issue of these cards or at what date this took place.
