Inflatable TARDIS
From Tardis Wiki, the free Doctor Who reference
As a result of early cash-flow problems on Doctor Who, at first there was an inflatable TARDIS instead of the proper prop. While the First Doctor attempted to blow it up, Ian Chesterton complained to somebody and stated that he didn't care if it cut down on storage costs.
