We present spectroscopic and photometric results for the Small Magellanic Cloud ( SMC ) cluster Bruck 88 .
From the comparison of the cluster integrated spectrum with template cluster spectra we found that the Milky Way globular cluster template spectra are the ones which best resemble it .
However , the extracted cluster colour magnitude diagram reveals that Bruck 88 is a young cluster ( log ( t ) = 8.1 \pm 0.1 ) .
The derived cluster age is compatible with the presence of a Bright Red Giant ( BRG ) star located \sim 2.6 arcsec in the sky from the cluster centre .
We serendipitously observed HW 33 , a star cluster located \approx 3 arcmin to the south-east from Bruck 88 .
We obtained for the cluster the same age than Bruck 88 and surprisingly , a BRG star located within the cluster radius also appears to be compatible with the cluster age .
We estimated the MK type of the BRG star in the Bruck 88 field to be in the range G9 II/Ib – K1 III .
By combining the spectrum of a star within this MK type range with a 100-150 Myr template cluster integrated spectrum , we found that a proportion 85/15 in the sense BRG/template results in a spectrum which best resembles that of Bruck 88 .
This result confirms that a BRG star dominates the cluster integrated spectrum , so that it causes the globular cluster appearance of its integrated light .
