Isn't the whole point of a cipher that it can't be solved without a copy of the cipher?
Not really, a lot of ciphers (Caesar, Rail-fence and even substitution ciphers, provided there is enough cipher-text to analyse) can be cracked either mentally or with pen and paper.
What you're thinking are bifids, trifids, ADFGVX ciphers and columnar transpositions that specifically require a key (word or square) to generate the transformer.
This is not strictly speaking a cipher, since OP's mentioned that every letter of the solution is in the 'cipher-text'. It's most likely a sectioned anagram or inter-element transposed affair... *shrug*
