Philatelic fakes and forgeries

In general, philatelic fakes and forgeries refers to labels that look like postage stamps but are not. Most have been produced to deceive or defraud. Learning to identify these can be a challenging branch of philately.
The practice of forging stamps began soon after they were first issued.
