And from a comment in the same thread as the second image (https://www.facebook.com/groups/86446817157/posts/10158212178342158/?comment_id=10158214049347158&__tn__=R*F): “original from 70’s was velvetta, can red pimentos, can diced green chilis, granulated garlic, canned jalapenos, half and half, fresh bell pepper…at that time portioned into the crocks in prep and microwaved on line. it changed to 1/2 pans when volume increased with expansion. velvetta changed to kraft pasteurized cheese spread or land of lakes golden velvet because velvetta was only in 1 lb blocks and cost saved by getting the large blocks.”
