Mama Tee's Fenton Glass

My mother-in-law (everyone called her Mama Tee) collected cranberry glass and I have three of her Fenton pieces. The first vase is a vintage cranberry spiral snow crest vase. The second piece is a cranberry opalescent hobnail candy dish. The last piece is a cranberry vase with a ruffled top. None of these pieces have markings, which means they were produced before 1970. Although Fenton has been in business since 1905, they didn't start marking their glassware until 1970. Other tidbits I learned from my research: Fenton's cranberry glass was introduced in the late 1930s, their cranberry opalescent glass was introduced in 1956, and the hobnail design is referred to as Fenton's "bread and butter" line.
