Color-composed stamps using the g and r bands centered on the three low-surface-brightness galaxies in which we detect a GC system. Stamps are 4 arcmin on a side. The spectroscopically confirmed GCs in RCP 12 (NGC 1052-DF4) and RCP 29 (NGC 1052-DF2) that are detectable in our data are marked with red circles. The GCs that appear after applying our photometric criteria are marked by green circles. We place a purple circle marking 3 × r_eff on RCP 32, which is barely visible in this color stamp.
