  We study the nature of the globular cluster (GC) candidates FSR 1603 and FSR
1755 selected from the catalogue of \citet{FSRcat}. Their properties are
investigated with 2MASS field-star decontaminated photometry, which is used to
build colour-magnitude diagrams (CMDs), and stellar radial density profiles
(RDPs). FSR 1603 has the open cluster (OC) Ruprecht 101 as optical counterpart,
and we show it to be a massive intermediate age cluster (IAC). Relevant
parameters of FSR 1603 are the age $\approx1$ Gyr, distance from the Sun
$\ds\approx2.7$ kpc, Galactocentric distance $\dgc\approx6.4$ kpc, core radius
$\rc\approx1.1$ pc, mass function slope $\chi\approx1.8$, observed stellar mass
(for stars with mass in the range $\rm 1.27 \ms\leq m\leq2.03 \ms$)
$\mObs\approx500 \ms$, and a total (extrapolated to $\rm m=0.08 \ms$) stellar
mass $\mTot\approx2300 \ms$. FSR 1755, on the other hand, is not a populous
cluster. It may be a sparse young cluster embedded in the H II region Sh2-3,
subject to an absorption $\aV\approx4.1$, located at $\ds\approx1.3$ kpc.
Important field-star contamination, spatially-variable heavy dust obscuration,
even in \ks, and gas emission characterise its field. A nearly vertical, sparse
blue stellar sequence shows up in the CMDs.
