The high galactic latitude planetary nebula 75+35°1 was observed in the low-dispersion mode of the IUE. The UV spectrum is characterized by a strong continuum that matches the energy distribution of a blackbody curve of 90,000K±5000K. A color temperature of 94,000K±4000K is derived. The spectral type mimics that of an O7.5 V star. A very strong N V λ1240 feature with a P Cygni profile is present. There is no trace of C III] λ1909 which is usually the strongest emission line in planetary nebulae. A very slight depression in the λ2200 region suggests very little interstellar absorption with an upper limit of E(B-V) = 0.025 mag, as would be expected for a high galactic latitude object. The ultraviolet observations, in context with the optical data, indicate that this object is not a typical planetary.
