This is a torn and restored paper trick. American magician Frank Lane was never shy about talking up the benefits of his routines. The advertisement pasted onto the front of the envelope is a good example. The third illustration here shows a close-up of it – it’s worth a read. The instructions, but not the advertisement, include the sentence: ‘No need, I suppose, to state this is a trick purely for stags.’ Performers would be wise to heed this advice.
