Info on oversized all occasion assortment by guys and gals

I have an old box of all occasion cards from the 1960s? I want to know more about these cards, not sure if you can help. The cards are OVERSIZED and in a box with a little baby girl playing a quitar. The only markings are on the box "Guys and Gals All Occasion Assortment $2.50 and the cards only have some info on the back - on L btm is a star; middle btm a succession of numbers and under that MADE IN THE U.S.A and on R btm is a number i.e. card 1 would have 1, card 2 would have card 2====not sure if anyone can tell me who produced them and/or the illustrator, thanks
