Identical catalog to Item # HK14 and it is marked "1/88" on the back cover........But included with this catalog is a 4 page Retail Price list which is dated "January 1,1989".The price list was with the catalog when acquired and I have not seen another HK Commercial Division catalog for 1989.So I believe the 1988 catalog was also the 1989 catalog with the 1989 Price List. Excellent As-New condition
