Broad-band photometry from 1-4 microns and low-resolution spectrometry, in the 2-micron atmospheric window, of the F-type supergiant CoD -61 deg 3326 equals Hz 747 are reported. The presence of an optically thin dust shell around this star is deduced and its properties are discussed with reference to the well-known yellow supergiant 89 Her. A similar post-main-sequence evolutionary status is proposed for both stars.
