Cards

	There are all kinds of cards which we use in our lifetime; although some are on the wane. One that is on the decline is the humble postcard. At one stage postcards became 3-D (Lenticular) which was very exciting.
	Greeting cards are also on the decline; and as any newsagent or card/gift-seller would agree, who would have ever thought would happen. Here are some examples of ‘70s Christmas cards.
	A postcard or is a rectangular piece of thick paper or thin cardboard intended for writing and mailing without an envelope. In some places, it is possible to send them for a lower fee than for a letter. The study and collecting of postcards is termed deltiology. The last and current postcard era, which began about 1939, is the “chrome” era, however these types of cards did not begin to dominate until about 1950. This postcard describes the phenomenon known as = Ferry the Human Frog.
	There are trading cards or swap cards which range from normal playing deck cards through to those that were colourful and illustrative and used for swapping.
	Then, there are those which were found as ‘”freebies” in packaged house-hold commodities such as petrol companies, numerous household packaged commodities like tea, cereal, bread or cigarettes.
