This is a Vintage AC Gilbert 1954 Erector Set "How to Make 'Em Book".  It is approx. 10 1/2" x 6 3/4".  It is in complete, intact, used condition.   Please, refer carefully to the photo / photos for the exact condition of this item. I consistently ship items out the next business day following the receipt of payment.  I generally ship daily except on weekends, holidays or when I am on buying trips or vacation trips. If payment is received by 10 a.m. central time, it will generally be shipped same day. If not, I will ship next day.  Always happy to combine shipping whenever possible, most of the time it will be the same cost as one item. Thanks and good luck!!
