Spy vs. Spy is a comic strip created by Antonio Prohias and published in Mad magazine. The two spies featured in the strip do not have official names or backstories, and as a result, there is no existing profile for them in the format of the Official Handbook of the Marvel Universe. However, I can create a fictional profile for the two spies based on their appearances in the comic strip:

Their exact first appearance was Mad #60. Normally I prefer to separate out characters but aside from their colour there isn't any real difference between the two spies.
