Thanks for your inquiry. We have only microfiche copies of the Fenton Glass catalogs, not originals. So they are not available to view online.
I was able to find the Lanb's Tongue pattern in the July 1954 Supplement catalog microfiche. It was released July 1, 1954, pattern no. 4301.
Attached is a copy of the supplement and an inventory page that includes that number with colors.
Hope these prove helpful. The images are black and white and not very clear on the mircofiche. I made the best quality I could and one of the images is enlarged to show detail.
