The photos are definitely taken at very different times: #23 has flowers in the grass that remind me of summer. #27 has bare trees that say winter or late fall/early spring (and the lack of leaves or snow on the ground snow and relatively light garments of the soldier(?) makes me think early spring). Same for #48 and #55. #44 has parasols, indicating summer.
