Hi, yes that is true, but don´t miss your chances in the future. I also don´t have big money like Scrroge McDuck, but i swap and sell some other copies from my private vinyl-collection, also other artists. So i can re-create some money for further DS gems. Yes i know such record-stores in Germany, small and big fleamarkets, house-clearances and so on. That are all good chances to grab some nice items.
But you need some special contacts for such exotic stuff. In Germany i find all the regular German issues, also special record-club-editions from the early DS albums as well, and sometime a cool UK- or a USA-issue in some collections but i detect the special stuff on the online marketplaces worldwide, or on some record-fairs.
