The research methodology was performed by studying the information in documented information and field data relating to the food culture and the existence of Lanna local foods. Furthermore, the research methodology consisted of analyzing artistic styles, design, and evaluating the efficiency of ready-made illustrations of Lanna local foods. The evaluation was conducted by 3 experts in graphic design and digital illustrations, along with the participation of 50 individuals, including students from the Graphic Design Program and graphic designers in Chiang Rai Province. The findings indicated that the Lanna local food designs could be categorized into 17 types: 1) curry (Kaeng), 2) roasted foods (Kao), 3) simmered foods (Khio), 4) sour soup (JOR), 5) Omelet (Jeaw), 6) pounded/mixed foods (Tam/Yam), 7) chili pastes (Nam prik), 8) steamed foods (Neung), 9) grilled/fried foods (yaang/Tod), 10) curry with squeezed crab juice or curry with local vegetables and herbs (Mob), 11) uncooked food (Larb/Lu), 12) mix vegetable or raw meat spicey salad (SAR), 13) fermented foods (mak/dong), 14) mixed foods, pickled foods, wrapping food in banana leaves and cooking in a pot or pan (Ok), 15) meat simmered on low heat (Uk/Hum), 16) wrapping food in banana leaves and grilling (Ab), and 17) dessert/snacks, totaling 127 menus. The researcher and experts studied and analyzed the features, and then designed illustrations. The results were web-based publications, digital media, calendar design, public relations media, souvenir products, and a picture book showcasing Lanna foods. Regarding the evaluation results on the efficiency of the use of ready-made illustrations of Lanna local foods and a picture book of Lanna foods, the identity area was at the highest level ($\overline{\mathrm{x}}=4.54$, S.D.=0.69); the beauty area was at the highest level ($\overline{\mathrm{X}}=4.59$, S.D. $=0.64$); the functionality area was at the highest level ($\overline{\mathrm{X}}=4.63$, S.D. $=0.59$)
