Vintage California Dreams Barbie partially used coloring book

Cover has some light spots front and back. Pages have yellowed...turning dark. Inside cover has pencil marks, stars drawn and it looks like some kind of insect was either drawn or stamped on. Slight dogear on front. 2 pages are colored and 1 has been partially colored. Small thin coloring book. 31 coloring pages...32 if you count the title page. I don't know if there were more pages originally but it doesn't say it's big like others found. There is no isbn barcode. I don't know if it was part of a set or is older or really why that is the case. Still a nice piece for a collection or to do more Barbie art. Book publisher is Golden but apparently not on the list I can type in. That's why it is branded unknown.
