The clothing styles, particularly the men's high lapels, bow ties, and the high lace-up boots on the right, strongly point to the late 1910s. The women's loose blouses with wide collars are also characteristic of the WWI era (circa 1915-1920). The candid snapshot style in a public park setting aligns with the popularization of consumer cameras during this period.

Three men in suits are seated in the foreground, with the center man smiling broadly and embracing the men on either side. Two women in light blouses stand behind them. In the background, there is a large, ornate glass conservatory building and some palm-like plants, suggesting a botanical garden or large public park.

Men are wearing three-piece suits, which was standard casual/outdoor wear for the era. The mix of neckties and bow ties is typical of the late 1910s. The high lace-up boots on the man on the right are a strong indicator of the 1910s, as lower oxfords became more common in the 1920s. The women's loose, unstructured blouses reflect the shift away from the rigid Edwardian silhouette during the WWI years.
