Set of 4 carnival glass tumblers with embossed grape and leaf pattern by Indiana Glass

This set of tumblers is part of Indiana Glass Company's 'Harvest Grape' pattern, produced primarily during the 1970s as part of the carnival glass revival. Indiana Glass, founded in 1907 in Dunkirk, Indiana, became one of America's leading producers of pressed glass and was particularly active in reviving carnival glass patterns during the mid-20th century. The iridescent finish and grape motif were inspired by early 20th-century carnival glass traditions. Carnival glass tumbler sets like these appeal to collectors of American pressed glass, vintage kitchenware enthusiasts, and those interested in mid-century decorative arts. The Harvest Grape pattern is particularly popular among carnival glass collectors for its attractive embossed design and rich iridescent colors. Complete sets are especially valued as they're ideal for display or actual use, making them sought after by both collectors and vintage home decor enthusiasts who appreciate the nostalgic charm and accessibility of mid-century American glassware.
