LAST CHANCE to get back issues of RTB Auction Catalogs. Great reference tools, well-illustrated and well-written, showing all manner of scarce cartridges and cartridge-related material. I purchased the entire stock of back issues many years ago, and have the following available:
Individual copies are $10, full sets of v10 thru 12 @ $25, post-paid to the lower 48. At some point in the near future I will be moving and they are NOT going with me, so this really is your last chance. Quantity discounts available!
